Would it be possible to separate the tk and tcl portions of tcltk into
two packages so that the tcltk package would be dependent on a new tcl
package ?  From the viewpoint of a user of tcltk there would be no
change but it would allow packages that only use tcl to declare a
dependency only on that.

By the way, tcl/tk 8.6 was released about 10 days ago with a ton of
attractive new features and it would be nice to have it in the R
windows build:
