i'll try to help as much as possible, although i haven't used red hat in a while (i had too many problems, and since it's not supported any more i figured i'd just quit using it altogether). assuming you're using redhat 8x (since your numpy pkg says rh8.0), try these:
http://rpm.pbone.net/index.php3?stat...reevo.i386.rpm
http://rpm.pbone.net/index.php3/stat....i386.rpm.html
and i think this will work if you already have version 2.3 of wxPython installed:
http://rpm.pbone.net/index.php3/stat....i386.rpm.html
but if you have 2.2 or 2.1, you will have to use one of these (respectively):
http://rpm.pbone.net/index.php3/stat....i386.rpm.html
http://rpm.pbone.net/index.php3/stat....i386.rpm.html
i'm not sure about pygtk; i didn't really find any rpms that were version 2 except this one:
http://rpm.pbone.net/index.php3/stat....i386.rpm.html
which wasn't explicitly for redhat 8 (the link says redhat
other), and i'm not sure if the fact that it's a devel pkg will throw it off. if i were you, i would recommend trying apt-get--a lot of redhat users like it a lot--or installing from source, which is actually easier than it sounds. good luck.
