The umfpack scikit provides wrappers of UMFPACK sparse direct solver to SciPy.

It should work both with the latest SVN, and the last releases versions of
NumPy and SciPy.

Installation on OSX
===================
- Download UMFPACK, UFconfig and AMD from
  http://www.cise.ufl.edu/research/sparse/umfpack/

- Unpack the archives in the same directory, so that you have
  src/AMD
     /UFconfig
     /UMFPACK

- Edit src/UFconfig/UFconfig.mk and remove -lgfortranbegin and -lg2c from
  BLAS::

    BLAS = -lblas -lgfortran #-lgfortranbegin -lg2c

- Go into src/UMFPACK and run "make"

- Copy src/UFconfig/UFconfig.h to src/UMFPACK/Includes

- Create a site.cfg in this directory (the root of the scikit), with::

    umfpack]
    include_dirs = /Users/stefan/src/UMFPACK/Include
    library_dirs = /Users/stefan/src/UMFPACK/Lib
    umfpack_libs = umfpack

    [amd]
    include_dirs = /Users/stefan/src/AMD/Include
    library_dirs = /Users/stefan/src/AMD/Lib
    amd_libs = amd

- Compile and install the scikit, using

  ::

    python setup.py install

    or

    python setup.py install --prefix=${HOME} # for local install
