I have a couple of pending package requests in bugzilla.fedora.us: https://bugzilla.fedora.us/show_bug.cgi?id=2329 and https://bugzilla.fedora.us/show_bug.cgi?id=2398 that I would like to help you close. The former (a library for visualization of 3D chemical structures) already had positive reviews, and I also included the suggested enhancements. The latter is just a port to FC3 of an already published (by livna) package: alleyoop, a gnome based frontend for valgrind. Better to submit the same requests to bugzilla.redhat.com so we can close to fedora.us ones? Cheers Gianluca
