GTK+ and Glib installation

[Chen, Douglas]

Hi,

Please forgive me if this is not the right forum to post question regarding library 
installation.

I tried to install a copy of Gtk+-2.6 in attempt to make Acrobat7 work on a Redhat
2.4.21-15.EL (WS release 3) machine and got error message during ./configure

It complained 

"for BASE_DEPENDENCIES ... Requested 'glib-2.0>=2.6.0' but version of GLib is 2.2.3

I then downloaded glib-2.8.5 and installed it (use default configure, make, and make install)
and tried to run ./configure under gtk+-2.6 again, but still got the same error message.

Do I need to do something more or set some variables in order to make it work. You help
is greatly appreciated.

Douglas
