Aehm, note that Apple has fixed the mmap(2) bug!!
I'm still surprised and can't really believe it, but it's true!
Just in case you're interested, i'll apply an updated patch.

Maybe Ned Deily should have a look at the version check, which
does not apply yet, but i don't know any other way to perform exact
version checking.  (Using 10.6.7 is not enough, it must be 10.7.0;
uname -a yet reports that all through, but no CPP symbol does!?)
