It would help if you provided enough code to actually run and demonstrate the problem. Given code demonstrating the problem it would also help to show the full error message - at... doesn't give much context for the error!

I notice that cpan testers don't show many passing combinations of OS and Perl version for the module (see http://matrix.cpantesters.org/?dist=Tcl-Tk+1.04). You may be better working with an alternative version of Tk? Tk is fairly commonly available and does better with the testers (http://matrix.cpantesters.org/?dist=Tk%20804.033).

Premature optimization is the root of all job security
