[pymvpa] Weave code broken on lenny

[Michael Hanke]

Hi folks,

I think I mentioned it before, but I want point it out on this
list, so it doesn't get lost:

The weave code in mvpa/clfs/distance.py cause the unittests on an
up-to-date Debian lenny to puke:

======================================================================

I am seeing this on multiple machines, so I would consider it a real bug
;-) However, I have no experience with weave and I am somewhat
clueless...

What about using cython to build a proper extension (at build-time)
instead of compiling stuff at runtime? Thoughts?


Cheers,

Michael
