[pypy-dev] Can't run any puppy tests, get --assert: invalid choice etc...

For instance this command :usage: py.test [options] [file_or_dir] [file_or_dir] [...]py.test: error: argument --assert: invalid choice: 'reinterp' (choose from 'rewrite', 'plain') Shubha D. Ramanishubharamani@gmail.com shubharamani@yahoo.com
