This seems like a problem we've been having when using pysparse in conjunction with pythonxy not enthought's python. How strange. I am not sure I can help you. I had the same problem, but it was resolved when I installed enthought instead of pythonxy. I think it is connected with the blas and lapack libraries and having the correct dlls or .a files available. You may want to venture down the path of building pysparse yourself (including blas and lapack) and trying to resolve the issue that way. Anyway, here are some things to try:
* Try running the uninstall scripts for both pythonxy and enthought. * Try deleting everything under C:\Pythonxy and install Enthough's python from scratch * Reinstall pysparse * Try "from pysparse import jdsym" Alternatively, try building your own version of pysparse along with blas and lapack. I can give you more instructions, just let me know.
