I would guess that she has everything on her system because her compile got
past the stage where headers are required and assuming that the qt stuff is
all shared libs, you would need those parts at run time.

BTW, since we know that KDE uses Qt, we can use some the tools at hand to
figure out what may be necessary:

I've never used KDE but I know that alot of the tools start with 'k' and it
probably has a mail client:

libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0x412ae000)

So on my system I would minimally need to add the following:

g++ -o testme testme.C -L/usr/lib/qt-2.3.1/lib -lqt

But I would expect that I very well may need to add other libraries as well
unless gcc is really good about picking up dependent shared libs.
