Building dbus-tqt, dbus-1-tqt, tqtinterface

In the 3.5.13.x branch, dbus-tqt and dbus-1-tqt were required to install to /usr rather than $PREFIX (usually /opt/trinity). In the R14 branch that was changed. At least, I have been building both to install to /opt/trinity since I started building R14 in the early days of the branch. * Are/should those packages be built to install to /usr? * Is tqtinterface still required to be built to install to /usr? * Are any other packages required to built to install to /usr? Thanks! :-) Darrell
