Comment:

 The error "`C preprocessor "/lib/cpp" fails sanity check`" has been
 observed in other ports before. When the configure script decides that
 "/lib/cpp" is the name of your C preprocessor (and then it fails, because
 that's not where OS X's C preprocessor ever is), it's because the
 configure script has tried all other common C preprocessor possibilities
 and decided they are unsuitable. I don't know why that is, but the usual
 fix for this has been to explicitly inform the configure script where the
 C preprocessor is, using "`configure.env-append CPP=${configure.cpp}`".
 I'll try to reproduce the issue, and see if that fixes it.
