The -arch i386 solved the qt error.

this is the latest version of qt downloaded fresh from trolltech

however, CGAL no longer compiles with -arch i386 because the rest of the libraries(boost, etc) are compiled by macports as x86_64 on os x 10.6

is the only way to solve this is to try to force macports to compile as -arch i386 also?

That is a very strange solution! There must be something wrong in that setup!
Maybe you should try to upgrade your Qt version, to see if that bug has been
corrected.

Actually, that is "-arch i386" that you need to add to your compiler flags.
"x86" alone is not a correct compiler flag.
