mlt failed to install

Hello, I am trying to install a video editor and found that most of them needs multimedia/mlt, so it first make conflict with archivers/freeze. I removed freeze and now it still does not install, it is giving me the next error. Any help please?.

Code:
usr/local/include/qt4/QtCore/qatomic_arch.h:96:4: error: #error "Qt has not been ported to this architecture"
gmake[2]: *** [depend] Error 1
