What version of Twisted are you using? I seem to remember something changing
in Twisted in the last few years w.r.t. OSError on OS-X.

Also, do Twisted's unit tests pass? (run 'trial twisted' and see if it
announces any errors).

It might be the case that PTYs just don't work on OS-X, but I think we've had
success with them in the past..

I suspect that as long as you don't use PTYs, this problem won't affect you.
That means that when you run 'buildbot create-slave', you should add the
'--usepty=0' argument to disable PTYs. (this controls whether child commands
are run inside a PTY or just with regular pipes for stdin and stdout).
