I have a working FC4 server (old, I know, but if it ain't broke don't
fix it) and I need to add a perl module required by another program. I
am not a PERL programmer.

What is the proper way to add a PERL module to such machine?

Is it as simple as untaring a tar file into a specific directory? If
the answer is yes, what is the name of that directory?

Thanks,
Sam

Usually by finding it at RPMforge, or EPEL repositories. Take a look at
http://rpm.pbone.net/ for the module you're looking for. Also, for a module
like 'NET::Ldap', you could use the yum syntax "yum info 'perl(NET::Ldap)' and
see what you get.

Thanks! I just discovered 'man perlmodinstall' and this is great. Here
is what it says:

======= START QUOTE ==========
First, are you sure that the module isn't already on your system? Try
"perl -MFoo -e 1". (Replace "Foo" with the name of the module; for
instance, "perl -MCGI::Carp -e 1".

If you don't see an error message, you have the module. (If you do
see an error message, it's still possible you have the module, but
that it's not in your path, which you can display with "perl -e "print
qq(@INC)"".) For the remainder of this document, we'll assume that
you really honestly truly lack an installed module, but have found it
on the CPAN.

So now you have a file ending in .tar.gz (or, less often, .zip). You
know there's a tasty module inside. There are four steps you must now
take:

DECOMPRESS the file UNPACK the file into a directory BUILD the module
(sometimes unnecessary) INSTALL the module.

Here's how to perform each step for each operating system. This is
<not> a substitute for reading the README and INSTALL files that might
have come with your module!
======== END QUOTE =========

I guest that I have some reading to do. :-)

Thanks!

NO-NO-NO-NO-NO!!!!!!!

Do not do this to any OS that uses packaging. You will confuse the tar out of
it, because it *will not know* that you have installed the module and
satisfied dependencies when you install other packages, and which version you
get will depend on your perl module path settings and whether components were
overwritten.

Please, for your own safety and sanity, use the published modules. If you have
to add modules, at least get 'cpan2rpm' as am RPM and use that to build new
RPM's with your Perl tarballs in them.

REading is good. Learning how Perl's MakeMaker works is also good, but please
don't discard your system's built-in package management. That way lies serious
instability.

Nico, thank you very much for raising my awareness to this.
Fortunately, I haven't done anything yet on my system so I am glad I
got to read your warning before doing low level stuff.

I have used 'yum' in the past. Assuming that I found an RPM that
contains the perl package in which I am interested (PDF:Reuse), what
would be the correct way to invoke yum to install it for me?

Thanks,
Sam

No problem. It's a common confusion: well-written packages have installation
procedures that RPM and Yum, or other tools like apt, live on top of.

If it matches the other components of your system, you should be able to use
'yum install [package.rm]', nad let Yum resolve the dependencies for you. You
may need to add a .repo file in /etc/yum.repos.d/ to point to whatever
additional repository you got the RPM file, to resolve those dependencies.
This is much cleaner than RedHat's old 'up2date' repository manager.

OK - I got to run 'yum' after a loooooooong time of not using it.
Invokes nice memories. :-)

First, I ran: wget http://www.fedorafaq.org/samples/yum.conf.
Then, I ran: yum check-update
Then, I ran: yum update perl

Which had the following result:

Now, I ran: /etc> yum info 'perl(NET::Ldap)'
Setting up repositories
Reading repository metadata in from local files

Then, I ran:
/etc> yum info 'perl(PDF::Reuse)'
Setting up repositories
Reading repository metadata in from local files

Does the fact that I received no info from this 'yum info' command
mean that those packages are NOT installed? or available?

Thanks,
Sam

Well, some more search yielded this:

http://www.cyberciti.biz/faq/how-do-...a-perl-module/

So, I tried:

/etc> perl -MCPAN -e shell

which started with:

/usr/lib/perl5/5.8.6/CPAN/Config.pm initialized.

then, it led through an entire interactive interview just to setup the
CPAN configuration.

I will try no to re-run the above yum install 'perl(PDF::Reuse)' and
see what happens.

Same thing happened. :-(

/etc> yum install 'perl(PDF::Reuse)'
Setting up Install Process
Setting up repositories
Reading repository metadata in from local files
Parsing package install arguments
No Match for argument: perl(PDF::Reuse)
Nothing to do

Will continue to research - unless the ultimate tip chimes in... :-)

OMG - did I hit a wall? It seems that I wasn't the first one to
encounter this challenge... Here is a thread from 3 years ago:

http://linux.derkeiler.com/Mailing-L...5-11/1263.html

Do I understand correctly that my only resort is to use CPAN?
directly?
