many thanks. Could I suggest that this information be featured 
prominently in the Read Me in the Installer, and perhaps also at 
http://www.scipy.org/Download where this is given as the official 
binary distribution for MacOSX. You might want to change the error 
message too, since I think that some people will interpret "System 
Python" to mean the default Python provided by the standard system 
install. Since this is 2.5.1 on Leopard, the error message could be 

On this topic, I would be interested to hear people's advice on using 
the system provided Python v an independent install. In 25 years of 
using Macs I have learned through several painful lessons that its 
wise to customize the system as little as possible: this minimizes 
both conflicts and reduces problems when doing system upgrades. I 
have therefore always used the default Python provided by OSX, so far 
with no obvious disadvantages for the types of scripts I use 
(primarily home written SciPy scientific code). However, I note that 
many people run either the pythomac.org distribution, or the 
ActiveState. What are the advantages to this?

Many thanks
