Continuing problem with xptcall on powerpc

Fri Apr 30 06:00:38 UTC 2010

 Forgive this constant barrage of questions from me.
/usr/ports/www/libxul/work/mozilla/xpcom/reflect/xptcall/src/md/unix
Warning appears with make and gmake.warning appears in bash and other shells.
Warning states, "XPTCall not implemented on this platform."
/usr/ports/www/libxul does not contain a patch for powerpc.
 Is anyone else using a G3 with these specifications: 400mHz, 384M RAM that has had a successful build? If so what options do I need to pass to make, gmake, automake, and autoconfig to use a patch- Where?- or to build a patch?
Thanks
