[kencu (Ken)]

why is this port selecting "clang" to use here, when building for PPC?

(If it is a base compiler selection issue, it would be very nice if we could stop that from happening centrally, rather than continue to add hundreds of workarounds for this issue in individual Portfiles that will all need to be stripped out again if we get this fixed.)

[kencu (Ken)]

this particular port seems to need some love anyway, as it is putting "-m64" and "-arch ppc" and "-DARCH_AMD64" on the same build line...

[tobypeterson]

Yeah, this port has major issues right now. I can't even build it properly on Apple silicon. Could be related to the wonky flags.
