I think only qt3 (=for me qt3-3.3.1) and qt3-devel are really necessary. In SuSE these packages come separately. The others are useful, though for other things. In particular qt-mt or qt-static are not needed here, correct? But I have them, too.
FYI I have got the libsig and libsigc-devel that are needed for inkscape 0.37. All of these are rpm. I install inkscape OK. bart at solozone.com
