IDLE : python 2.2 on RH 7.2

[A.M.]

Hi,
I just set up a linux box with RH 7.2 and then upgraded python from
2.1 to 2.2
After I was done I tried to start up IDLE and the version number it
showed me was 1.5.2. On doing an rpmfind I realized that RH 7.2 come
with both python 1.5.2 and 2.1 but uses 1.5.2 for most of the stuff...

Now when I try to start up the IDLE in the /usr/lib/python2.2/Tools
dir it deosnt start up. How do i get IDLE with both python version to
run or at least switch between the two python versions or at least get
2.2 running.

Is there a conf file I can look up or something..

I installed using RPMs and did a : 
rpm -Uv py*;
It installed all right and I can start the interpreter by typing in
python2. How do I get IDLE working for 2.2???
 
The error I get when I try to run the IDLE in 2.2 :

[aseem at michelangelo]# ./idle
Traceback (innermost last):
    File "./idle", line 5, in ?
        from idlelib import IdleConf
ImportError: No module named idlelib

Where is this idlelib, how come it doesnt give me an error when I do
the same in python 1.5.2.

Almost the same thing happens when I do a python idle.py

But this time with a module called warnings.

Any help would be greatly appreciated...
Thanks,
Aseem
