Not exactly. I've cross-compiled ppc binaries that were able to  
register. But the user complained that sound was distorted inspite of  
the fact that it was good on my Intel Mac in Rosetta emulation. And  
when he builds pjproject natively, everything is fine.

That distorted sound build had been made by me with the following steps.

$ ln -s /usr/bin/powerpc-apple-darwin9-gcc-4.0.1 /usr/bin/powerpc- 
apple-darwin9-gcc
$ ln -s /usr/bin/ar /usr/bin/powerpc-apple-darwin9-ar
$ ln -s /usr/bin/ranlib /usr/bin/powerpc-apple-darwin9-ranlib

$ ./configure --host=powerpc-apple-darwin9 --build=powerpc

Edit build/rules.mak. Change one line:
-	$(RANLIB) $(LIB)
+	$(RANLIB) -o $(LIB) $(OBJS)

$ make dep
$ make

Maybe this is some byte-ordering problem, since PowerPC is big-endian  
and i386 is little-endian? Or maybe I'm cross-compiling it incorrectly?
