Hi Robin,

I am using umfpackv4.4 without any problems.
I have compiled and installed umfpack from scratch.

My site.cfg consists of

[amd]
library_dirs=/home/nwagner/src/UMFPACKv4.4/AMD/Lib
include_dirs=/home/nwagner/src/UMFPACKv4.4/AMD/Include

[umfpack]
library_dirs=/home/nwagner/src/UMFPACKv4.4/UMFPACK/Lib
include_dirs=/home/nwagner/src/UMFPACKv4.4/UMFPACK/Include

Now umfpack is a scikits package

svn co http://svn.scipy.org/svn/scikits/trunk/umfpack 
umfpack

Cheers,

         Nils
