Comment:

 Reading the file build/macos.inc in the source, it expects the `arch`
 variable to be one of "ia32", "intel64", "ppc32" pr "ppc64".

 Reading the portfile, it sets the arch_flag variable to "intel32",
 "intel64", "ppc" or "ppc64".

 So it appears the port is doing the right thing on 64-bit Intel and
 PowerPC systems, but the wrong thing on 32-bit Intel or PowerPC systems.

 Ticket #23944 about PowerPC build problems with tbb remains open.
