Hi all, I encountered the same problem with pysparse on windows. I have rebuilt pysparse using pysparse-1.2-dev203 with mingw for python 2.6.5 and also for python 2.5 on windows xp. pysparse still crashes in both cases: "from pysparse import precon" works, however "from pysparse import itsolvers" gives DLL load failed (from pysparse.itsolvers import krylov). Apparently there is a problem with the built krylov dll in windows. Therefore I still use the binary pysparse-1.1.win32-py2.5.exe for installing pysparse for python 2.5 which gives no problems.
