Comment(by Peter_Dyballa@…):

 Replying to [comment:7 ryandesign@…]:
 > r88037 (see duplicate #32552) was another attempt to fix this but it
 does not change the error message for me.

 I took some time to investigate further. If GALLIUM is the problem on PPC
 then Mesa-7.11/src/mesa/Makefile might need a patch. Its line #6 has

 {{{
 MESA_LIBS := libmesa.a libmesagallium.a
 }}}

 By commenting libmesagallium.a the build process should proceed. I tried
 it kind of manually. It led from the state with the failure to another
 error with not finding X11 libraries. I'm trying this with a new patch
 file (Gallium-PPC.patch), and port will need some hours, either to succeed
 or to fail again, so here is the patch:

 {{{
