I wasn't clear enough in my explaination.  I still search directories for the
*Config.sh files, but I generalized it so that a list of TCL and TK versions do not have to be maintained.  Here is the segment of code that performs the search for tclConfig.sh:

    library_dirs="$LIBRARY_DIRS /usr/lib"
    TCL_CONFIG_SH=
    for dir in $library_dirs; do
        if test -d "$dir" -a -r "$dir/tclConfig.sh"; then
            TCL_CONFIG_SH=$dir/tclConfig.sh
            break
        fi
        for tcl_dir in $dir/tcl[0-9]*.[0-9]*
        do
            if test -d "$tcl_dir" -a -r "$tcl_dir/tclConfig.sh"
            then
                TCL_CONFIG_SH=$tcl_dir/tclConfig.sh
                break 2
            fi
        done
    done

OK.  That clears things up, now.  But ...

   Here is the segment of code that performs the search for
   tclConfig.sh:

	   for tcl_dir in $dir/tcl[0-9]*.[0-9]*
	   do
	   ...
	   done

I think that this will fail by finding the LOWER version of tcl
before a higher version.  For example, if I have both 7.6 and 8.0
installed, won't this find 7.6 first?

Might there not be installations with an old version lying around?

Should the script be enhanced to at least report on ALL versions
found?

Should the script simply assign for each version found, rather than
breaking out of the loop?  That might have a better chance at catching
the highest version; although, it doesn't won't order 8.9 and 8.10
correctly.

Cheers,
Brook

Sorry, I've lost track of the discussion. Is it the case that people
know that pgtcl does not install at the moment? On my machine the
installation procedure has trouble finding one of the shell files under
discussion...

This is news to me.  The current code looks for tclConfig.sh and
tkConfig.sh in the various standard directories.  In my case, they are
in /usr/contrib/lib.  Can you add the directory that has those file to
your search path include dirs.

If you can assume that Tcl is installed and the version the user wants
is first in their path, you should be able to limit this to

    library_dirs=`echo 'puts $auto_path' | tclsh`
