What we did in addition for our software is to add these options to the 
Qt configure:

   -buildkey namexyz -no-rpath -R $ORIGIN

This was used to prevent 'our' QtCore4.so (?) from loading 
system-installed plugins that in turn tried to use a different version 
of the Qt shared objects.

Thiago, please comment on this if it happens to be complete nonsense... :-)
