Hi Joerg,
qt/qmake 3.3.3 was released today. Unfortunately the delopers did not
include your patch for qmake, so the override needs some trivial fixes.
The only thing I had to do was change the PORTVERSION to 3.3.3 in
the qmake Makefile, and copy over 'distfiles' from the FreeBSD qmake
directory.
The entire qt upgrade doesn't affect the i386 arch at all, AFAICT,
so the only reason to fix this is to keep portupgrade from complaining.
