Check what qmake -v gives you. 
also
ls -l /usr/bin/qmake*
I saw the same errors, but my system is
setup in a non standard way. i.e
qmake is a symlink to either qmake-qt5 or qmake-qt4 depending. It's
switched by a script i wrote.

For me the solution was to change qmake to qmake-qt4 in the SlackBuild.
