Hi Xavier, I think this is a great idea. I have sold other people on
numpy/scipy, but myriad BLAS/LAPACK/fortran combinations makes the
installation process unpleasant for new users.

The "right" way to do this is to put a [umfpack] section in site.cfg
Ideally, auto-detection would always include knowledge about where the
major distributions put these files. Keep in mind that scipy's
support for UMFPACK is deprecated in 0.7 and has been moved to a

For 2) you can either improve the auto-detection (I don't know how
myself) or simply not use UMFPACK. The danger is that someone might
already have libsuitesparse-dev installed, so fixing the
auto-detection is probably a better approach.
Anyway, I'm eager to see this information become available. Do you
plan to provide instructions for both 32-bit and 64-bit versions? In
8.04 I believe there were some differences in the availability of BLAS
libraries between the two.
