OK. This should get things mostly fixed, though (it makes PPC work).
Thanks for your work here!

It's actually a make error, sorry:
make: "/usr/ports/x11/pixman/Makefile" line 23: Malformed conditional (!
${MACHINE_CPU:Mmmx})
make: "/usr/ports/x11/pixman/Makefile" line 26: Malformed conditional (!
${MACHINE_CPU:Msse2})
make: Fatal errors encountered -- cannot continue
make: stopped in /usr/ports/x11/pixman

I can give you a shell on a PPC machine if you'd like.
