PowerPC 32bit is still work in progress. PowerPC64 bit is 
supposed to work. But there is an issue with 0.13.0 release which 
is fixed in master branch.

This seems to be an issue with root/port.c. If these functions 
are missing then the conditions to choose the implementation are 
not complete.

I have some patches for PowerPC 32 bit:
http://www.redstar.de/ldc/ppc_druntime.diff
http://www.redstar.de/ldc/ppc_phobos.diff

They try to fix some parts and comment out not yet working 
asserts. std.math is notorius here.
