I can now successfully pip install from the git repository. I was actually able to get it working a few days after I posted by using:

  CFLAGS="" pip install git+git://pysparse.git.sourceforge.net/gitroot/pysparse/pysparse#egg=pysparse

This issue (at the time) was that some of the headers from suite-sparse were being found instead of the ones included with pysparse.

After several reconstructions of my Homebrew installation (for other reasons) I find I no longer need to pass `CFLAGS=""`. I don't know why it used to be necessary and now is not.

What does *not* work is 

  pip install pysparse

which raises

    cc: pysparse/sparse/src/spmatrixmodule.c
    pysparse/sparse/src/spmatrixmodule.c:4:10: fatal error: 'spmatrix.h' file not found
    #include "spmatrix.h"

The tarball at https://pypi.python.org/pypi/pysparse is incomplete (missing pysparse/includes is the one that raises the errors, but there is a bunch of other stuff missing) and the tarball does not seem to correspond to any revision in the git repository, e.g., pysparse/direct/setup.py has a number of uses of

  os.path.join(cwd,...

that do not appear (specifically the inclusion of `cwd` in the join) anywhere in the git history.
