Tres argues for the easy_install case. If you don't have a meta-egg that 
does the same as a versions section in a buildout, how do you get the 
same versions each time?

If you *do* have a meta-egg, how do you override just one egg that you 
need to replace for, say, a security fix?

Fair enough...
