And they consider good practice to go into a system directory and run
make? I don't think so. And if they do, It is really really bad...

If qt3 is installed, there should be no need to build $(MOC).
moc should be built by qt3-x11 (at least, qt3-mac does and puts it in
/opt/local/bin/). In principle, QT Apps should build provided you tell
them QTDIR=/opt/local (put ${prefix} instead of /opt/local) and if
needed tweak the Makefile to tell where the bins and libs are
($QTDIR/bin and $QTDIR/lib/qt3 I suppose).
