Good point, I added a note to the scipy download page.

Agreed, the message is confusing.  I'll fix that on the next release.

We should leave the System Python to Apple.  They use it, and have
numpy 1.0.1 installed with it.  Installing your own python with your
own packages (numpy 1.1, scipy, etc...) provides a clean division and
is less likely to create conflicts.

>From  http://developer.apple.com/tools/installerpolicy.html

" Off Limits
The folder /System is for Apple use only. It holds important operating
system files, and everyone using the machine relies on this folder.
Apple-provided system libraries and file systems live here. If you do
not know if your software belongs in here, chances are that it does
not. Mucking around in /System can lead to machine instability."

Thanks for your feedback,
Chris
