tcl + tk on FC4

[Dave Gutteridge <dave@xxxxxxxxxxxxxxx>]

I'm about the embark on trying once again to get my linux wacom to work 
in FC4.

Last time I tried this, I went through various stops and starts until I 
realized I didn't have tcl + tk on my system. Since I've reinstalled 
FC4, I want to make sure I have tcl + tk installed first.

I went to the sourcefourge page for tcl + tk, but I noticed there were 
no RPMs for it. Last time I installed them, I recall I was able to find 
an RPM that had everything I needed. I also Googled for options with 
yum, but was unhelpful.

How can I:
Check if tcl + tk are present and running
and/or
Install tcl + tk if needed?
