I had this exact same problem. I needed python 2.5 but had etch. I do not recommend to install python 2.5 from aptitude since it is not the newest version available. Here are the steps I took...
* Simply download and install the latest python from source. It is very easy to do.
- This installs it to /usr/local/ so it is separate from python 2.4 installed in etch.
- Now, whenever you type 'python' or 'easy_install' it automatically refers to the python 2.5 you installed in /usr/local since debian by default has /usr/local before /usr/bin in your PATH variable.
* Now, you can install any package you like using easy_install and you have a separate python 2.5 and you don't have to worry about symlinks, default python, etc.
I have using this on a production etch machine without any problems.
Let me know if you need further help or more detailed instructions.
