Really? qt4 packages in RHEL5 are built with --prefix=/usr/lib/qt4
and almost everything is put there. What makes it impossible to build
another instance of Qt4 with different prefix and perhaps a small
discriminator in sonames?

I have looked at http://svn.rpmforge.net/svn/trunk/rpms/vlc/vlc-test.spec

I see:

--- cut ---
### Workaround to make -lX11 work on 64bit
export LDFLAGS="-L/usr/X11R6/%{_lib}"
export QTDIR="$(/usr/bin/pkg-config --variable=prefix QtGui)"
export PATH="$QTDIR/bin:$PATH"
export QTINC="$QTDIR/include"
export QTLIB="$QTDIR/lib"

--- cut ---

So, if we build a Qt under ie. /usr/lib/vlc/qt4 and change the above QTDIR (from /usr/lib/qt4) - will this work?
