 Thank you. If you don't mind, condition it on `build.arch` being `ppc
 ppc64` - that won't prevent building on 10.6 PPC and 10.6.8 Rosetta
 (conditioning on `os.arch` will break it for Rosetta).

 `/usr/include/errno.h`.

 How should I fix that? In build files?
 Headers should be standard, this is on 10.5.8 with Xcode 3.1.4, nothing
 weird.
