Can you elaborate on why PKG_CONFIG_PATH=/usr/X11R6/lib/pkgconfig is needed? We usually don't link against system X11 libs in MacPorts, but rather depend on and link against the appropriate xorg-* port. See wiki:FAQ#ownlibs.

That line is taken from the SWI-Prolog developer instructions for Mac OS X. I'm not familiar with PKG_CONFIG. Tested the patch before submitting. Everything seems fine. Your suggested alternative would be?

Talked with the SWI-Prolog developer today. It seems to be safe to drop /usr/X11R6/lib/pkgconfig from the definition of the PKG_CONFIG_PATH environment variable. Already replaced the patch applying this change.

I've commited this for now in r90316.

I think I have a few points where the portfile can be improved (e.g. building with clang might work), but I'll just put it on my todo list and open a ticket as soon as I have a tested patch.

Building with clang does work but it kills performance. Apparently, due to poor support for GCC threaded code. The same thing happens with e.g. YAP, another Prolog compiler. The best performance in both cases is achieved using a recent version of GCC.

Btw, can you also take care of committing the update to the "swi-prolog-devel" port? Thanks.
