Thank you very much!
It is ugly, but it'll do until GWT itself is fixed. A note for others
trying this -- I believe some of the formatting got mangled in the
post. The last command should be:
for bin in `find . -type f -exec file {} \; | grep 'Mach-O universal
binary with 2 architectures' | sed -e 's/:.*//' ` ; do ditto --rsrc --
arch i386 $bin $bin.tmp.app ; mv $bin.tmp.app $bin ; done
