Never tried, but we should be able to work through this.

What file is being complained about? At what stage? I haven't  
completely reviewed the quartz gtk, gdk, pango, and cairo code yet,  
but it's possible that there are parts that use Carbon, which might  
produce just that error at link time as Carbon doesn't support 64-bit.

Are you setting the -arch x86_64 flags before doing anything else?  
(I.e., rm -rf ~/gtk, do the exports, then jhbuild bootstrap etc.)

Have you looked at the compile commands in the output to make sure  
that the -arch flag is correctly passed to gcc, and that it's the only  
arch flag? (That's important, because if gcc gets two arch flags, it  
will try to do a universal build. Glib and gtk+ can't be built  
universal that way (they use assembly); they have to be built  
separately for each architecture and lipo-ed together.)
