tar doesn't compile yum. Your best results would be to get the RPM version for your OS. Try visiting www.atomicrocketturtle.com (Click Downloads, go through Atomic, then your OS version (2 is FC2, 4 is FC4, etc.). Locate the RPM, right click, and copy the link location. Then wget it, and issue an rpm -Uvh <the filename here>.
Alternatively, you can locate the RPM through rpmfind.net or another source. I don't limit myself to just one source, though I find that ART (atomicrocketturtle.com) seems to have 99.9% of what I need/want.
