Ahhhh, sorry, I forgot one important thing... variants are evaluated
*after* the rest of the Portfile (in order to resolve conflicts and
requires first). So this configure.cmd is evaluated before the variants
and therefore qt_dir is not set to what you expected.

If configure.cmd is all you want to change it would be way easier to
just use this inside the variant directly.

variant qt4 conflicts qt3 description {Use qt4-mac} {
    depends_lib-append port:qt4-mac
    configure.cmd ${prefix}/libexec/qt4-mac/bin/qmake
}
