Half the fun is figuring out which version of GM or IM (IM being most common) is broken on any particular OS.

Does it say you're using IM or GM in Xastir's Help->About?

It's possible that when you recompiled, it couldn't find the -devel package for GM and so compiled in IM.  Or vice-versa.

In any case, check, then add the proper -devel packages and libraries and re-compile.  9 chances out of 10 that will fix your problem.
