[mythtv-users] Why can't loader find this library? It's there.

Getting an error during make (loader can't find qt-mt):

> g++ -shared -Wl,-soname,libmythavcodec-0.18.1.so.0 -o libmythavcodec-0.18.1.so.0.18.1 ...
> ... -L/usr/share/qt3/lib -L/usr/X11R6/lib -lqt-mt ...

> /usr/bin/ld: cannot find -lqt-mt

But given the command includes "-L /usr/share/qt3/lib"
and tries to load the qt library with "-lqt-mt" ...

... then it should be able to find /usr/share/qt3/lib/libqt-mt.s0...
if that file is there.

It is (see below).  It's a symlink up to the actual file in /usr/lib.
So why the loader error?  I'm confused.
