The only issue at this point is the distribution of mingw dlls. I have not found a way to do it nicely (where nicely means something that is distributed within numpy package). Given that those dlls are actually versioned and seem to have a strong versioning policy, maybe we can just install them inside the python installation ? cheers, David _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
