Fgrun-1.5.2 has trouble finding the Open Scene Graph library libsgbvh.so becuase its name changed. Not sure if I didn't compile osg correctly for linux but what i got was a bunch of shared plugins in /usr/local/lib/osgPlugins-2.8.2. None of their names start with lib so the linker can't find them.
If you do something like this:
ln -s /usr/local/lib/osgPlugins-2.8.2/osgdb_bvh.so /usr/local/lib/libsgbvh.so
it will compile and link just fine. You could also edit src/Makefile.am, and src/Makefile.in to rename sgbvh to osgdb_bvh.
