Dumb and fundamental questions, glib 1.2.8 install

[elvisnixon <elvisnixon mindspring com>]

I am currently running RH 6.1, and I am installing glib 1.2.8 so that I
can
install gtk+ 1.2.8.  After I have run "configure" and  "make" for glib,
I then run
configure for gtk.  I then get a message that it requires glib1.2.8 or
greater.
The current version of glib available on my system is 1.2.5.

Which directories should I untar glib 1.2.8 and gtk+ 1.2.8 from?  Which
path should I enter into "etc/ld.so.conf", or  how should I configure
other files?  Any other tips?

Thanks
Jason
