Thanks for looking at my problem. I don't have anything relevant under 
/usr/local -- the search paths are built into the package.

I also have access to a Debian system with tk 8.6.0+8 installed. On this 
system, I run tclsh and type

set auto_path

and get

/usr/share/tcltk/tcl8.6 /usr/share/tcltk /usr/lib /usr/local/lib/tcltk 
/usr/local/share/tcltk /usr/lib/tcltk/x86_64-linux-gnu /usr/lib/tcltk 
/usr/lib/tcltk/tcl8.6

and then running

package require Tk

returns 8.6.2 and opens a toplevel Tk window.

Now on my own system with tk 8.6.0+9I run tclsh and type

set auto_path

and get

/usr/local/lib/tcl8.6 /usr/local/lib /usr/lib

If I then type

set auto_path {/usr/share/tcltk/tcl8.6 /usr/share/tcltk /usr/lib 
/usr/local/lib/tcltk /usr/local/share/tcltk 
/usr/lib/tcltk/x86_64-linux-gnu /usr/lib/tcltk /usr/lib/tcltk/tcl8.6}

(so it is the same as it was in 8.6.0+8) then

package require Tk

it returns 8.6.6 and opens a toplevel window. I have added a line to my 
script to set the auto_path to the old value and my application now runs 
OK, although tk and wish should not need this.
Cheers
