Python script problem on Mac OSX

[GoogleCodeExporter]

What steps will reproduce the problem?
1. The program was untared in /Applications/XDS-OSX_Intel and this folder was 
then sourced in .bash_login. Xcode and X11 are fully up-to-date but when xdsme 
is executed there is a problem with python scrip subprocess.py. I have tried 
copying this python script from Phenix, but this did not work either.

3.

What is the expected output? What do you see instead?
I would expect XDS to run to completion, however I get the following.
