Trouble with idle from python 2.4.2 on SUSE linux 9.3

[Alasdair]

I've just installed python 2.4.2 from source - it works fine from the
command line.  But when I attempt to start idle, I am told:

** IDLE can't import Tkinter.  Your Python may not be configured for
Tk. **

I have tcl 8.4 and tk 8.4 on my system; can anybody provide me with
some advice?

Sorry if this is a FAQ; I've spent some time searching the net for
helpful clues, and I am a python ultra-newbie.

Thanks,
Alasdair
