Fink is a
SourceForge project to produce and distribute binary
packages for MacOS X environments. They provide packages for Tcl/Tk - see:
http://fink.sourceforge.net/pdb/package.php/tcltk
and
Expect:
http://fink.sourceforge.net/pdb/package.php/expect
among others.
Perhaps someone on the wiki can work with these folk to get some of the other useful extensions packaged up?
