Yes, that is what made me think that a new recipe might be the only
way, where the recipe would put numpy on the path during the develop

Yes, if numpy is already on the path, it works, but we wanted to test
against several different numpy versions, and it seemed ugly and
fragile to make a separate virtualenv for each python / numpy version
pair. We'd much rather use the buildout mechanism to specify these,

Actually, no, not in this case, it is only used as a crude dependency
check. But, for other packages we have, we do need numpy.distutils
for the setup.py - for example to find the numpy include directory for
compiling C modules. The only reason I was offering this package as
an example is that it is rather small and easy to install compared to
Thanks a lot,
