[I'm surprised it's in /lib64.]

I'm on RH6, not Fedora, but I'm successfully using a 1.6.5 package built
with a modified (for extra config options) Fedora spec file. It
dynamically links against an hwloc 1.7 package (not the original system
hwloc version), but I don't know if that makes a difference.

I agree about the value of OS packages and libraries -- money where
mouth is, maintaining packaging for SGE against hwloc etc.
