Also, where does "whereis moc" show on your build system?
whereis moc moc: /usr/bin/moc /usr/X11R6/bin/moc /usr/bin/X11/moc /usr/X11/bin/moc /opt/trinity/bin/moc
I'm not sure how smart the build system is at the moment. Try symlinking /usr/bin/moc and /opt/trinity/bin/moc to the real TQt3 moc that is residing in /opt/trinity/lib/tqt3-R14.0.0/bin/moc. Remember to make clean before trying to rebuild, as the build system will not detect that the moc binary has changed and recreate the .moc files.
