set default python interpreter to 2.5- How do i do it?

[Lithonite]

Currently the default is set to 2.4.4 which installed with sys

I just pulled down the source for 2.5.2, and i would like to make it the default for my environment. Looked through wiki and could not find the answer( no i cannot" just emerge python " - as one python-2.5.1.r5 cant be found... )

So having pulled down the latest python, i would like to now well, set it as my default so i can make use of executable .py scripts i have via the 2.5 interpreter.

I dont know how to do this, and I do not want to try and pull and "ln -s" maneuver if possible.

There appears to be an eselect-python package. You could try that.

If you installed python-2.5 via emerge, it will be the system python. After that, you'll need to run python-updater to update anything that creates python modules. Once you've done that, run python --version and see what it says.

I don't have eselect-python installed, and have been using python-2.5 since it hit unstable with no problems.

Thanks for the replies guys... As mentioned above emerge of python FAILS as a file its pointing does not exist in the directory its pulling from.
I have manually pulled down python 2.5 - and i certainly can execute it and run against it.

I just want to make python 2.5 the default interpreter when i type "Python" or when i "./" on an executable .py file.
I'll do python-updater once "python -v" returns with data from the 2.5.2 build.

From what i can tell all i need is to be able to set my already already pulled down and executable binary of python2.5 as my default python instance.

But i cant find where the heck to set, this. When emerge pulls this down its updating environment variables to let it know that python 2.5 is the new default. How do i do this command line style?
