When making an ELF shared library, it should be done like this:
ld -shared -o libx.so.x.y.z -soname libx.so.x <object files>
If not done like that, the ELF library has no internal information on its
version. That is why when you run ldconfig, it links libforms.so.0.81 to
itself, and not libforms.so.0, like it should.
Try to recompile your library, and use the "-soname libforms.so.0" option
when linking to fix this problem.
