That's clear i had the same problem long time ago,
and i written a small wrapper to the blitz library (www.oonumerics.org):
i hadn't time to iron out all the details so it isn't ready for general
release, but it works.
I'm courrently using some sort of template skeleton to write modules in
python for my phd (it is 4d digital image processing): if you like to help
me to develop it in a usable way this should be useful for other people as

I think someone else has developed such a glue, under scipy (isn't?): just
look at that.
