For any gentoo users out there, a umfpack ebuild is available here: 
http://gentooscience.org/browser/overlay/sci-libs/umfpack.

I was able to build scipy with umfpack support on an 64bit Athlon machine 
using this ebuild, which provides version 4.6 with support to build shared 
libraries. No changes to site.cfg were necessary.

scipy.test() and scipy.linsolve.umfpack.test() were both successful.
