I have installed ActiveState's Python 3 packages on Mac OS X 10.6.6.

When I run the Mac OS installer it shows all disks as ineligible and the error message, "numpy 1.5.1 can't be installed on this disk. numpy requires System Python 2.6 to install."

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.

That message comes from bdist_mpkg. I fixed it on my machine, and a fix was also committed to the svn repo. However, I think there was no new bdist_mpkg release on pypi (I did get a "why don't you just use eggs instead?") and the 1.5.1 binaries were not made on my machine. So the problem returned.

What can I do to persuade numpy to install? Must I build it from source to get it to use Python 3?

Yes, there is no binary for Python 3 at the moment. But unless you have a specific need/desire to use 3.1/3.2 I'd suggest staying with 2.6 or 2.7 from python.org for now. With Activestate you have to compile yourself or use their (paid?) pypm repo. Cheers, Ralf
