When having trouble while installing an egg during the installation phase(easy_install time)

Now the recipe can display some information about which wanted this distribution.

This is even more useful that it support up to 6 dependencies levels from direct to parents !

Here is an example:

We see at first shot that easyshop give us trouble ! Without, its hard to know which distribution want ssl-for-setuptools :)
