Rob,

Thanks for the feedback. #1 has been on my list for a long time but
never gets adressed because time is scarce. I really want to have a
proper setup.py for Pysparse. I'm now getting better at writing them
so maybe I can whip up something quick.

Regarding #2, could you be more specific? In my experience,
package-specific include files always go to the include/ directory of
the local Python environment. However, you can normally install
packages "locally" (e.g., in your home directory) instead of system
wide, by using an option such as --prefix or --home with setup.py. I
might have misunderstood your question...

Cheers,
