Yes. You can start tclsh and run 'set auto_path'. This will print out
a list of the directories that will be searched for packages.

I had a discussion with upstream about this, and they blamed the problem
on the distributions installing Tcl and the extensions into too-generic
directories. Unfortunately, most extensions were developed to be
installed directly into /usr/lib and /usr/share, and now need to be
patched to be installed elsewhere.
In any case, you can always look at the contents of the auto_path
variable on any platform in Tcl to see where extensions are looked for.
