bro, check this out.
goto Redhat startup menu, then click on system settings and then Add/Remove programs, kinda like old fashion windows.
once that opens up, save yourself some time and install ALL of the Development packages, the program will ask for CDs that you will need to enter. Then run the Up2Date and make sure that all your packages are up2date.
PS. also goto http://gtk.org
and download gtk+-2.2.2.tar.gz, this is the newest GTK+ package, I had a lot of problem until I downloaded this.
PS. I have only been doing linux for about a week or 2 now, and I find my self grabbing Source instead of RPMs.
