wished "wish"



Hi again,

On my freshly installed Fedora 5 I have installed:
tk.i386 0:8.4.12-1.2 
tclx.i386 0:8.4.0-1.2 

If I type "xmaxima" I still get:

/usr/bin/xmaxima: line 3: exec: wish: not found


In the directory /usr/bin there is no wish command.
Where can I find the wished "wish"?

Googling "wish" hasn't helped me, either...

Any suggestions?
