I agree it is slightly inconvenient for users to set an environment variable
so this should ultimately be fixed.

What specifically do you suggest?  I was tempted to put a "." in the list
that Vince mentioned above, but I wasn't sure that was the right syntax to
use or even if tcl experts such as yourself really did want the local
directory always searched for this file or if so, in what order? For
example, there might be security implications in always automatically
searching the current directory first (or at all) since it is a very similar
situation to putting "." in your path.  Anyhow, I would appreciate you and
Vince thinking about all this and making the final decision.

Until this minor fix is finalized, setting the environment variable should
be okay for testing purposes on CVS.

When you actually try the latest CVS version are there any other concerns
that need to be addressed?
