I can confirm that this simple fix did it for me. As for a patch to the port itself, please find an archive, "port-patch.tar.gz", attached. In it, you'll find the Portfile patch (in files-patch/), as well as the patch file (in files-add/) that needs to be added.

[royliu@…]

A patch for the port itself.

[stefan@…]

A can confirm that the patch + port-patch fixes the problem.

qt 4.6.0 (the current version of qt4-mac) already contains the necessary fix, so this bug is fixed.
