This file is missing. I would google it.

You cannot run a tcl (Task Control Language) file through sh, you must install and use "tclsh" for those:

Quote:

Tcl, developed by Dr. John Ousterhout, is a simple to use text-based script language with many built-in features which make it especially nice for writing interactive scripts.

How to do that in Cygwin I wouldn't know, the above quote is from a real linux distro (package for Slackware, to be exact).
