appears to fail on trying to use python 2.5 which is not installed

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Doubleclick app after installing 1.3.1
2.Previous install has not tested before removing and replacing with 1.3.1
3.

What is the expected output? What do you see instead?
Standard mac os dialog for crashed app. "namebench cannot be opened due to a 
problem

I suspect the app is looking for python 2.5 which is not installed and not 
using the current or default install of python

What version of the product are you using? On what operating system?
1.31
active version of python switches between python 2.7 and python26-apple the 
standard apple install.

chrisd@cd:~$ python_select -l
Available versions:
current none python26 python26-apple python27

Please provide any additional information below.
due to fault with install of python i don't think i have an older python 
install of 2.5 on my machine.
