[Distutils] How to make an egg easy_installable ?

[David Cournapeau]

Hi,

    I wanted to make an egg from my package, so that people install it 
with easy_install. I managed to make an egg, which works fine, but I 
have problems with the cheeseshop, and how easy_install retrieve the egg.
    First, I uploaded the egg using register and upload command, and I 
can see the egg on the cheeseshop. But when trying to use easy_install, 
it does not work: it tries to look for packages in at the URL I gave in 
url argument, and do not take the egg from the cheeseshop.
    As a temporary "fix", I removed url and url_download arguments, and 
re-upload my package: this time, easy_install get the egg, but fails 
installing it:

And at this point, I am lost :)
