>From a couple minutes of poking around: strings /usr/lib/qt4/libQtCore.so | grep Build.key strings some-other-file | grep buildkey Which comes back with seemingly everything build against Qt4... But I don't know how to tell which ones qualify as a "plug-in"... Typically when I rebuild Qt4 I also rebuild kdelibs, PyQt4, and my themes... in my case that is gtk-engines-kde4, gtk-engines-qt, and all qtcurve packages. Seems to work for me.
