Hmm... I am pretty shure these applications (mainly qt3 and pango) do not use 
these functions directly. They use public functions which call the non-public 
functions. This is why I can recompile these apps with freetype 2.1.x without 
problem (if all those source rpms where build properly - which is not the 
case, e.g. after recompiling qt3 kdm crashes, after recompiling pango one 
libpangoxft is missing which prevents GTK apps from starting).

Just to show you the problem with libpango:
ldd -r /usr/lib/libpangoft2-1.0.so.0
        libgobject-2.0.so.0 => /usr/lib/libgobject-2.0.so.0 (0x40048000)

        libglib-2.0.so.0 => /usr/lib/libglib-2.0.so.0 (0x40088000)
        libpango-1.0.so.0 => /usr/lib/libpango-1.0.so.0 (0x400f3000)
