Great - that's good news.

Seo has provided a patched version which skips the (broken) checking of 
varargs and varkeywargs from the standard library version. (Which does 
bytecode inspection and so hasn't a hope in heck of working on alternate 
implementations of Python).

We'd have to see what else needs changing - but probably not too much.
