OK. I'll first try some other solutions first.   ;-)

No, I wasn't sure. But now I am. I followed your suggestion -- same
problem!

  make[4]: Entering directory `/home/m/kde/qt-copy/tutorial/t1'

  $ objdump --syms /home/m/kde/qt-copy/lib/libqt.so|grep qPRCleanup

All listed paths are correct, yet it doesn't work. Damn! (Sorry ... ;-)
Are there some debugging tools, that I could try?
