Comment (by barracuda156):

 Replying to [comment:1 ryandesign]:
 > It's trying to use Intel assembly code even though you're trying to
 build for PowerPC. Find out why it's trying to do that and how to tell it
 to use PowerPC assembly (or no assembly) instead.

 There must be some Macports `.tcl` file somewhere which handles build-
 host-target, linker and assembler assignment, I will try to find it.

 (One reason some ports ''might'' try using i686 code is if they have a
 wrong setting for Xcode 4.x as if it cannot support PPC. I am quite sure I
 had zero problems with all these basic ports when building on 10.6 PPC. On
 10.6.8 with Rosetta it turned to be harder, so far.)
