Are you using the 0.7.1 source code zip file? I'll have to try it again, but I believe it compiled ok when I tested the build instructions.
It almost sounds as if the libQt5Widgets.so.5.0.1 is corrupt, as if there was a problem downloading Qt. But if you installed it ok, it sounds unlikely. What do you get if you run
Code:
file /opt/Qt5.0.1/5.0.1/gcc/lib/libQt5Widgets.so.5.0.1
Try a make clean, then recompile. Might not help, but gives you plenty of time for a cup of tea
