Can not run Python's IDE 'IDLE' on Fedora 6

["Bo Xie" <xiebopublic@xxxxxxxxx>]

I have installed tk and tcl by 'yum install tk/tcl'.
---------
# pwd
/usr/lib/python2.4/idlelib
# python idle.pyw
** IDLE can't import Tkinter. Your Python may not  be configured for Tk. **
---------
How to run 'IDLE' in Fedora 6 i386?

Thanks!
