A couple of things to note:

- pytest requires python v2.6+ so these changes would have to wait until
after Roundup v1.5.1 is release (the last to support python v2.5) before
they can be pushed to the repository 

- the new pytest run_tests.py script will automatically search for tests
to run, so if you have a virtualenv directory in the local repository
clone directory you should probably invoke the script using:

  ./run_tests.py test

to specify that you only want pytest to look in the test/ directory for
tests.
