What was here? Was there a long list of directories that
you trimmed away when posting?

If not something is very very weird.

If so, then you trimmed exactly the part that might allow
me to help you.

Please state exactly what Tcl you installed. Where did it come
from, and what version did it claim to be?

That's the last-resort workaround, you will always have available,
but with a proper install, it ought not be needed.

Even if your install programs can't be solved, you can always
take care of the issue within the code of your "toy tcl/tk program".
