1) The gtk module fails to load on Solaris 9 and later platforms.

   Check LD_LIBRARY_PATH in your environment.  If it contains /usr/lib
   then the dynamic linker may be picking up the default Gtk libraries
   bundled with Solaris, which are probably older than the version
   against which SLgtk was built.  Unset LD_LIBRARY_PATH and try again.
