Peter, 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. Best,
