I can't see how ghc can generate a correct executable if you pass  
these cross-compilation options to GHC.  Even if you can get GHC to  
generate proper PPC code, it will link against *Haskell* libraries  
that contain i386 code.  (The options -optl-arch -optlppc will give  
you the PPC versions of the system libraries, but not the GHC  
packages.)  Or am I missing something?

According to Wolfgang Thaller's answer to a previous post by yourself,  
these atom sorting errors are harmless:
