Vicky,

Your CFLAGS and LDFLAGS settings appear that you're trying to compile a 
"fat" binary on MacOS. Is this true?

If so, I don't think MacOS supports a 32 bit JRE any more. I'm not 
certain, since I don't have a Macintosh, but some people at $work do. 
They indicate that they can no longer run applets in Chrome (32 bit) but 
require Firefox or Safari (64 bit).

What happens when you don't use those flags (or at least not the -arch 
386 for those flags)?

. . . just my two cents
