In FreeBSD, wish is named with a version number. This is becauseQuote
different versions of wish are not compatible with each other and
they can not all be called "wish"! You may need multiple versions
installed because a given port may depend on a specific version.
On your system, wish is installed under at least the following names:
wish8.2
wish8.3
wishstep8.0
So, I changed the sh-bang to
#!/usr/local/bin/wish8.3
and it works. [/quote]
