Because the original post is discussing the scenario where you are 
installing an egg that was already built by someone else.  You're correct 
that the fetch_build_eggs() method can and should just use the attribute 
directly.

I'll take it for a spin.  It looks pretty good, except that easy_install 
doesn't use it.  I can go ahead and add that bit.  The doc is a bit, um, 
terse, but I can flesh it out a bit I guess.  :)

You don't need to; it's the easy_install command that needs to do that, in 
process_distribution() I believe.

That's where build dependencies are supposed to go, actually; building and 
testing a package shouldn't cause build-time dependencies to be permanently 
installed on the build system, without an explicit action.  You can always 
"easy_install *.egg" if you want to make them permanent.

Yes; it should get passed to the find_links argument given to the 
easy_install command instance created by Distribution.fetch_build_eggs(), 
which is what your patch does.
