I discovered today (some bug reports have hinted at this but didn't spell it out completely) that I forgot Mac OS 10 testing for numarray-0.6. As it turns out, the numarray examples and add-ons don't compile correctly due to a small untested change.
I corrected the problem and uploaded a new tarball to Source Forge:
http://osdn.dl.sourceforge.net/sourceforge/numpy/numarray-0.6.1.tar.gz
Non-Mac users of numarray-0.6 should just ignore numarray-0.6.1. This is a source update only.
