Compile JPL on Mac

I want to compile JPL on my Mac having the following problem:

plld -embed-shared -o libjpl.dylib src/c/jpl.o -Wl,-framework,JavaVM
ld: in /opt/local/lib/libxml2.2.dylib, file is not of required  
architecture

The libxml has no PPC code inside (checked it with nm -arch...) and  
plld wants to build for both, INTEL and PPC.

So I want alter the Makefile to force plld with  -ld-options* to use  
only something like -arch i386?
Has anyone a workaround?

Mit freundlichen Grüßen / Best Regards
