I did the install for the PDK 6.0.  I copied the sample from the
documentation

use PerlTray;
  sub PopupMenu {
      return [["ActiveState", "Execute 'http://www.ActiveState.com'"],
        ["Exit", "exit"],
       ];
  }

I pointed to the script and set the build directory for the same
directory.  When I build, I get the message that perltray.pm can not be
found. In fact, I am unable to find perltray.pm on my system.
