True, the current state is very confusing for users.

Well, for most cases different Tcl/Tk version are interchangeable.
Though having one
default version is a good idea.

This doesn't affect libraries much, but definitely affects application
which use /usr/bin/tclsh as
an interpreter. They will have to depend on tcl, and not tclX.Y, where
there wouldn't be /usr/bin/tclsh.

Unfortunately, there're still bug which prevent using threaded expect
on hppa. (http://article.gmane.org/gmane.linux.ports.parisc/2478) It
isn't fixed yet. So, I don't think we can drop Tcl/Tk 8.3 now. May be
can switch Tcl/Tk 8.4 to non-threaded build and add expect-tcl8.4?
