I believe it should.

I think there are plusses and minuses to this approach.  It would
certainly solve the problem of "we want to update a dependency but the
build server wont see it".  On the other hand it might not gracefully
handle the "updating a dependency requires a clean rebuild" issues.

There are times when it's nice to be able to use your already-built
dependencies.  Then there are times when it would be nice to be able to
use the new ones.  I guess the down side is that we're at the mercy of
the upstream provides to continue to publish their "older" versions of
our dependencies.

How often do our dependency download URLs go bad?

(FYI, I believe this change, if you make it, should NOT be back ported)
