Pango / glib nonsense continues...

[Anthony <orders nodivisions com>]

To recap: I installed Slackware 9.0 two weeks ago, which included glib 
2.2.1.  Now I'm trying to install Gnome 2.4, which means I need to 
install glib 2.2.3.

After installing glib 2.2.3, I get to the "install Pango" step, but 
Pango complains that it's found both glib 2.2.3 and 2.2.1.

I run Slackware's pkgtool and remove glib 2.2.1.  It tells me that it 
was removed.

Re-run Pango's configure script, and now it says it can't find glib at all.

Re-install glib 2.2.3 (using the default location which is /usr/local), 
then re-run Pango's configure script, which still says it can't find 
glib at all.

Re-install glib 2.2.3, this time with --prefix=/usr, which is where glib 
2.2.1 had been installed.  Re-run Pango's configure script, and now it 
tells me that it AGAIN sees BOTH versions of glib, 2.2.3 and 2.2.1.

How can Pango possibly be finding v2.2.1, when I REMOVED it, and then 
installed 2.2.3 ON TOP OF where it the old version used to be??

Can anyone help me sort out this crap, or else just kill me?  Thanks.
