Comment(by craigcitro):
I think that's a race condition -- I suspect two calls to build_ext
simultaneously realize that there's no directory to store a file and try
to create it at the same time. The first is okay, but the second gets an
error and bails.
The attached patch should fix this, as long as that's what's going on --
it creates all the appropriate directories in `build/` while processing
files in serial, thereby eliminating the potential race problem.
