I am using slackware 9.1 on x86, and wanting to try out some of
the latest gnome developer packages.

So the pkg-config 0.90 tar.gz is downloaded and it builds and
installs ok (over the old 0.14 version).

Then I download the glib-2.3.5 tar.gz and
try ./configure .
It breaks off the configure with an error:
"*** pkg-config too old; version 0.14 or better required."

After playing with this for quite sometime (updating
config.guess and config.sub, autoconf, experimenting with
manual changes, etc) it appears pkg-config cannot handle:

> pkg-config --atleast-pkgconfig-version 0.14

This returns false when it should return true.
Anyone know what is happening and can point me in the
right direction?
