File /usr/local/bin/qucs has these missing library files:
libqt-mt.so.3
libqt-mt.so.3 is the multithread shared dll from QT3.
dingo has a partial qt4 install under /opt/qt4
I've been fighting qt3 vs qt4 a lot myself (it's a bigger mess than even M$ could make).
at one point i tried to symlink libqt-mt.so.3 to the main qt4 dll as it has mutlithreading built in by default but ended up with some weird errors.
a lot of qt apps still require 3 but I think that will change as I read somewhere that there was a licensing change between qt3 and qt4 of some type. not sure if it was accurate but it seemed to indicate that qt3 was no longer free and required a licensing fee of some type.
Sorry no fix for the problem, just wanted to shed some light for you.
your best bet is to try and get someone to compile those apps for qt4 (if they support it).
