There was a push to put tqtinterface in /usr (I don't have the reason), so that is what I've done, basically building with: [ "$QTDIR" = "" ] && . /etc/profile.d/tqt3.sh _prefix=/usr _tdedir=/opt/trinity mkdir -p build cd build cmake "../tqtinterface" \ -DCMAKE_INSTALL_PREFIX=${_prefix} \ -DQT_PREFIX_DIR=${QTDIR} \ -DQT_INCLUDE_DIR=${QTDIR}/include \ -DMOC_EXECUTABLE=${QTDIR}/bin/moc \ -DQT_VERSION=3 make > > This is in part because moc-tqt cannot be found.

That I understand. No point to fine to be drawn. I would like to see the packages flexible enough to be put anywhere. Either in /opt, /usr, or where ever.

The more help like this you can give, the quicker they will be found and fixed.
