Very strange... as if the ptlib weren't linked in...

Well, here is how it is supposed to work:
* gm is launched;
* gm is linked to the pwlib, hence it is loaded;
* a plugin is loaded, through the very same lib;
* since the lib is already linked in, the plugin finds the symbols;
* it works!
I really can't understand how gm could find the ptlib to launch the
manager, but couldn't find it to link the plugins! Did you compile with
some special option?
