I looked over your diffs but I don't think they're related to the
problem you're seeing.
>From your previous posts and those of Sebastian, I had the impression
that you're using numarray in an embedded context... so I found
embedded "from numarray import *".
I learned that numarray embedding "broke" for numarray-1.2.3 by adding
the unnecessary requirement that sys.argv exist. I fixed this in
numarray CVS. A possible alternative to my fix which should work for
older versions of numarray is to call PySys_SetArgv(0,NULL) after
Py_Initialize() to ensure that sys.argv exists.
Regards,
Todd
