Yes, but other tests (like test_rosdep, test_rosmake) are Python as 
well, and pass.

I've brought back the "from __future__ import with_statement". If 
someone want to test with Python 2.5...

Just out of curiosity, why do you want to stick to Python 2.5 for
Diamondback? Python 2.6 is standard on Linux distrib since a while
(at least Ubuntu 9.10), and 100% compatible with Python 2.5...

Yes, the first batch of patches only target the 'ros' stack. I've 
splitted the original patch in one patch per tool in the trac ticket.

Here we are:
