Haha, now Clang failing. Okay, this time we have to fix it properly. Gimme a bit.

UPD. PG chooses OpenBLAS on these systems, but passes only -DBLA_VENDOR=OpenBLAS, which is not recognized. I will fix it now.

@herbygillot Looks good now. Finally :)

UPD. And the last thing, added blacklist of {clang < 500}, it fails on 10.7: https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/130314/steps/install-port/logs/stdio
