[Numpy-discussion] 1.1.0 OSX Installer Fails Under 10.5.3?

[J. Stark]

I have just tried to run the 1.1.0 OSX installer on a MacBookAir 
running 10.5.3 and the installer fails with

"You cannot install numpy 1.1.0 on this volume. numpy requires System 
Python 2.5 to install."

The system python version reports as

jaroslav$ python
Python 2.5.1 (r251:54863, Apr 15 2008, 22:57:26)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin

which is the same version that Leopard has had all along, as far as I 
am aware. On the the other hand, there have been some reports on 
PythonMac about odd python behaviour following the 10.5.3 upgrade.

Has anybody used this installer successfully under 10.5.3, and/or 
have any idea of what is going on.

Incidentally, this is a new machine with just the default system installation.
