How did you install the previous version?
Or can't you uninstall the old version and then install the new version?

A thing you could do:

Uninstall the 0.91 version.
Now on a shell prompt type "which gtk-gnutella"
For me this outputs "/usr/local/bin/gtk-gnutella" for your system it may be different. If it doesnt output anything at all, say it.

If it outputs something, delete that filename it outputs. Then install the rpm for 0.91.1 (its newer and better than 0.91) and it should work
