If the rpm supplied in Fedora works, then why compile it yourself?

Couple of questions though.

Where did you get the source from?

And, have you checked the logs?

General observation: Building from source doesn't mean you
built it the same way. There are often a gazillion ifdefs
in source code. Might want to download the fedora source rpm
and see what flags the spec file uses to build.
