I did this the other day (self evident when I did my first build). this is
not the problem.
the problem is that -L/usr/lib is before all other -L params in a generated
this means that it will grab say
libmythtv-0.22.so from this dir ahead of the one in the build tree.
since the one installed in /usr/lib is build with the previous qt3 builder,
it is not valid and has missing symbols. thus the link fails.
so far I havent figured out why qmake-qt4 puts this -L/usr/lib ahead of all
other lib paths.
