Errors when doing 'use Tk::ExecuteCommand'

I get the following error when my script starts up:

Proc::ProcessTable missing, can't kill sub-children. at
/usr/local/lib/perl5/site_perl/5.8.8/aix/Proc/Killfam.pm line 19.
 at /usr/local/lib/perl5/site_perl/5.8.8/aix/Proc/Killfam.pm line 19

The start of my script is:

   #!/usr/bin/perl
   use Tk;
   use Tk::ExecuteCommand;
   use Proc::ProcessTable;
   use Tk::MiniCalendar;
   use Tk::LabFrame;
   use Tk::FBox;
   use Tk::LabEntry;

I am running on AIX 5.3 using perl version 5.8.8.  I added the following
modules with no errors reported:

Proc-ProcessTable-0.41
Tk-ExecuteCommand-1.6

I seem to be able to ignore the error and continue to run the script.  But
I would like to not have these errors show up.

Anybody know what is happening?
