I guess my question is

1. is 3.3 preferred for some reason by the Centos framework? If a

program looks for "qt-mt.pc", does that mean it wishes to use qt3.3 rather than qt4?

what program are we talking about?

2. aside from just hand editing that file and changing the prefix to

/usr/lib/qt4, how do I change the preferred QT. The qt4-devel package gives its own set of pc files, but I can't tell how they can be used in the environment..

add the following lines to .bash_profile in your home directory (or lib64 for 64bit), should make qt4 default for that user export QTDIR=/usr/lib/qt4 export QMAKESPEC=/usr/share/qt4/mkspecs/linux-g++/ PATH=$PATH:$HOME/bin:{QTDIR}/bin
