You probably need at least libtk-devel and libtcl-devel to build with tkinter.

Sorry as i already said i'm new to linux and python. Previously i worked with windows and had no problems. Can you please tell me how to get and install the above mentioned packages.. Your help is much appreciated...

In the applications menu of your desktop panel, you select install software (you need the root password for this). This opens the software manager, which has a search form. Put libtcl in the search form, then check the package you want in the list. Then click on the button at the bottom of the widget to install the package. Repeat with libtk.
Then go to your python source dir and try to rebuild.

Millions of thanks gribouillis for your reply again. I've searched my install & remove software repository. You've mentioned about two library files. As far as libtk is concerned it's ok. Please see the pic. http://i37.tinypic.com/2mgktc2.jpg. But when i searched for libtcl it shows like this http://i33.tinypic.com/orrm7d.jpg. For this i've inserted the mandriva DVD and installed the rpm for libtcl. But still the status is the same. what should i do now?
Sorry dude if u think that i'm asking silly questions. But i'm really new to linux. It's not like windows where you could double click all the the objects and know the outcome and gain the experience from it. I can't make myself in tune with "first know to how do it and then start working " concept of linux. you know it took me more hours to figure out how to install tarball files.

And one more ques. what is rebuild? Is it like uninstalling and installing again (in windows terminology) or repeating make,make test and configure steps? Please make me clear...

I said that you need libtk-devel and libtcl-devel if you want to build with tkinter. If the libraries don't show in the list, you must check that your rpm sources configuration is good: open the mandriva control center (it should be System->Administration->Configure your computer, sorry I have a french localisation, so I don't know the exact name of the menu entries in english). In the Control center, you go to software management and select configure the sources (before doing this, close your package manager). On my system I have the sources HTTP Main, HTTP Main updates HTTP Main32, HTTP Main32 updates HTTP contrib, HTTP contrib updates, HTTP non-free and HTTP non-free updates.
I can't build python 3 with tkinter here because I have a 64 bits processor and I read that it won't work...

You must run the software installer when your internet connection is working . In principle you don"t need the cdrom.
By the way, I'm sure that you never COMPILED python on windows. When mandriva will have a rpm for python 3, it will be as easy to install as it is on windows.

Also note that it should be available soon, as this page proves. But I don't think you should try to install these packages on 2009 spring. So when 2010 is out, if you upgrade your system, you should have a python 3 with tkinter.

thanks again gribouillis for ur reply.. when i clicked s/w management i got a window like this.. http://i35.tinypic.com/muzgi1.jpg. Whewn i clicked the configure media to my surprise the window i saw was http://i37.tinypic.com/2va1glf.jpg. I can't see a thing like HTTP free non-free or stuffs like that. I think the thread is getting lenthier . Tell me what to do now?
And one more imp. thing here is when i searched a solution for this problem in google i found the second link to this thread. Such is the power and impact of this community. It's not going to be useful only for me but for trillions of users too. So keep going. Thumbs up bro!!!

Did you try to click on the "add" button in your last picture ?

Also note that python mandriva is shipped by default with python2.6. Is there any possibility of conflict between these two libraries? As said by PSF 3.x is not backward compatible with 2.x versions????
