I think if you copied the files from one machine to another, and get that error, it means that the underlying c libraries are different on the machines, and there is an incompatible situation. You cannot just copy files compiled on 1 machine, with dynamic library linking, and expect them to work on another machine.

Compile and install Tk yourself, from the source tarball available at cpan. It is one of the smoothest and easiest source tarballs to build.
