Upgrading and modules

[Brian Elmegaard]

Hi,

Every time I upgrade python I also have to download all packages and
reinstall them.

http://www.voidspace.org.uk/python/articles/upgrading_python.html
tells me that this is only a problem on windows for some reasons that
have to do with binary distributions, compiling and more. 

This leads me to the questions:
1: Isn't there a better way? 
2: Why is compilation needed for installation of a package? 
3: Why isn't python backwards compatible so reinstallation is
unneeded?
4: Would it help if python was compiled with gcc/mingw so installation
would be the same as on other systems?
5: What about a package repository and a manager like miktex has?

regards,
