You'll need to build tcl/tk in the "unix" mode instead of the native win32
mode.

You may run into one or two little problems, but if you have X11 
development libraries/includes and all that, you can just configure and
build the whole thing in the {tcl,tk}/unix directories. See Scriptics
web site for Unix configuration/installation help.

However, before you build Cygwin Tcl/Tk as Unix, you'll need to apply
a few trivial patches. I remember that Sergey Okhapkin had those on
his web page at http://www.lexa.ru/sos/
