Great timing, I was planning to write about this just a few minutes
ago. I didn't investigate which commit broke it. I have prepared a
tiny patch that I applied locally. basically, on top of the header
file:

#if defined(__APPLE__)
#include_next<_types.h>
#endif

I guess we can address this issue either with something like my patch
or by skipping installation on darwin.
