And pango doesn't complain that harfbuzz needs graphite2?
Is graphite pulled in some other way?

Which in particular?

That's what it did before, unconditionally.
Are there any 32-bit Intel Macs out there? Is pkgsrc supposed to support them?

That's obviously the case here. I was getting compiler errors about C++11 
features being used.

It's a bug in pkgsrc that packages need to declare the minimum GCC version 
when compiler.mk could deduce that from USE_LANGUAGES. Why only GCC and not 
Clang or PCC or whatever?
I wrote a patch to do that automatically (for GCC) ages ago.

OK.
