execute.py failed on Gentoo using python 3.2

[GoogleCodeExporter]

Hi guys, I'm running a nice fresh gentoo installation on one of my machines and 
I'm busy setting up fern on it. The default python version was 3.2. Upon 
executing execute.py, it threw an import error when loading in the commands 
module. Shock and horror, upstream have been messing with the libraries again. 
Apparently, you should be calling subprocess instead. Switching over to 
python2.7 resolved that particular issue. Any chance you could look at 
resolving this?

Hi, noticed you're looking at this when I a fresh version out this morning. If 
you've not already tried it, I think replacing line 7:

import commands

with:

if(sys.version_info.major==3):
        import subprocess
else:
        import commands

Might go some way to allowing execution under both versions of python. The 
interpreter seems happy enough, but I'll have to wait until I finish PyQt 
compiled into Python 3.2 before I can confirm this.
