Comment (by kencu):

 Looks like with some motivation we might get OpenBLAS to build on PPC
 (there is a Power makefile to use as a starting point). Dunno if there is
 any interest. I just tried for a lark and got nowhere with the current
 Portfile.

 I have only seen the AR & RANLIB errors on 10.6 and less so far, and only
 with newer clangs (3.9+). But enabling it in all cases for systems < 10.7
 seems like an easy fix and harmless to me. Another thing it would be nice
 to do in base, if all builds respected those env vars.
