I am trying to configure a gnutella client (gtk-gnutella-0.92.1c), and I can't get the configure script to run correctly. It stops telling me that it A) can't find the gtk-config file (and neither can I), and B) it can't find a version of GTK >= 1.2.0. Seems like I need to install GTK, but when I do an rpm -qa | grep gtk I get (among other things) the following two results...

gtk+-1.2.10-25
gtk2-2.2.1-4

I have no idea what GTK is, but this seems suspect. What should I do? Is there another rpm that I need to install?

ok heres the thing that not to ovious,
1) GTK2 is not compatible with GTK+

so when it says GTK >= 1.2.0 it realy means GTK >= 1.2.0 && GTK < 2.x.x
as for that other gtk thing u got (gtk+-1.2.10-25), its oviously not installed corectly (this is gonna mess you up (to put it nicely), as you MUST COPLETLY remove gtk+-1.2.10-25 from you system (espically the libs), if you dont then a reinstall will fail cuse it wont overwirte the alrdy installed parts, then get the gtk sources for 1.2.9? (realy whatever you want but it must be greater then 8 as thats the verson required by the gimp (unless you want to get the rpm's wich i guess youll like mroe sence you used
rpm -qa | grep gtk
after you isntall the rpm's and its still dont work then go delet the gtk libs and program and other fiels it installed, then install from source as source is much more realible then rpm
