This is on OS-X, under tox. Neither the buildbot nor travis is showing this one.

Same problem (and fix) as #250: a leftover foolscap/ directory. We recently moved all the source files from foolscap/ to src/foolscap/ (specifically to avoid confusing leftover .pyc files like this), but when making the transition, you need to delete the old directory manually.
