Hi,

I tried building from the scikits package with exactly the same
results (no umfpack stuff in __umfpack.so, just Py* stuff and a couple
of _gfortran symbols.

The umfpack version I am using is the current from the website - I
think it is 5. I don't think the site.cfg is the problem, since the
headers and libraries are found OK (If I move them then they aren't
found and the build fails).
Somehow the problem must be with what distutils is doing to build the
__umfpack.so object? Is there any way I can get more detail about
this?

Below is the output of setup.py config for the umfpack scikit...
