You don't need the ActiveState Tcl distribution to add extensions. If you
compile extensions yourself (and these extensions have a compatible
license), then you have no problems... (well, almost! You must make sure
those extensions compile correctly on all supproted platforms). This is
exactly what I do in the tcltk2 package.
