Sorry, that is is a bad error message. What I'm pretty sure it means to 
say is:

"numpy requires the Python 2.6 binary from python.org "

I looked at this error message ages ago, and It's less trivial to fix 
that you'd think -- but I thought it had been fixed.

You *may* need the python.org binary, rather than ActiveState, but it 
looks like you're trying to install a numpy binary for 2.6 -- that's not 
going to work on 3.* -- look for a binary for 3.* -- I'm not sure it 
exists, though.

NOTE: if you're still confused, tell us exactly what file you are trying 
to install from, and where you downloaded it from.
