[mythtv-users] missing -lqt-mt

Sorry for the off list reply. You need to have built qt with the
-threads option passed to ./configure

Also make sure you've got all the QT environment variables set and that
ld can find the libs. You might need to add the /path/to/qt/lib to
/etc/ld.so.conf and run ldconfig.
