The lustre plugin wouldn't run for me in python 2.7.3 so I rewrote
some of the parsing code to update it for this version of python.
I'm not that familiar with differences in python over time, so I'm
not sure when the changes happened that caused this to fail to
compile. I also have not tested my fix against other versions of
python.
