現状ではqt4-qmake-4.8.7_2がインストールされてます。
んでBROKENになる前のavidemux-plugins 2.6.11_1をmakeすると次のようになります。

===> Installing for qt4-qmake-4.8.7
===> Checking if qt4-qmake already installed
===> qt4-qmake-4.8.7 is already installed
You may wish to ``make deinstall'' and install this port again
by ``make reinstall'' to upgrade it properly.
If you really wish to overwrite the old port of qt4-qmake
without deleting it first, set the variable "FORCE_PKG_REGISTER"
in your environment or the "make install" command line.
