Hello Eddie,

There are no environment variables to set in Pysparse, so no, you
haven't missed any.

Could you please post the complete output of 'python setup.py build'
as well as the result of 'ls -l
/software/ATLAS/3.8.3/lib/liblapack.so'? I don't doubt your word that
the library is there but am just trying to get the obvious things out
of the way first. Also I presume you can run the ATLAS and LAPACK
tests with your libraries?

Thanks,
