portfile test for macosx 10.6.8 + libc++

[Ken Cunningham]

Hello everyone,

I'd like to help with minor porfile adjustments to allow compiling on the above system, within my limited skill set.

To allow for an accurate method of specifying a system running 10.6..8 + libc++, can anyone help me with a good test spec to run in a portfile?

Do you also think that same test should apply also to 10.7 with libc++, in most cases, ie lump them together?

Thanks,

Ken
