Thanks, I've corrected the problem. The referenced line in the error is below. This is part of "Widget.pm". After some frustration I thought back to the CPAN install of the Tk module and remembered that though everything finally installed it had some issues in finding some of the c headers required to compile. I thought I had corrected the problem and that the installation had completed successfully. But just in case I removed the module; insured all the required header and lib files were in the right directories and reloaded the module through CPAN. Now everthing appears to function correctly. I can't point to just what the issue was in the first installation but assume that one of compilations failed and only produced a warning and the install progressed.
