>Description:
        When you run a `make update' in pkgsrc on a pkg that has a dependency
        which needs to be rebuilt, when the dependency build fails,
        the pkgs which share that dependency won't get built again when the
        dependency build is restarted.
>How-To-Repeat:
        Pick a pkg which has a dependency which needs to be updated.  Let's
        say graphics/imlib2 needs to be updated and we are calling
        `make update' on wm/enlightenment (which has imlib2 as a requirement).
        Suppose we also have eterm installed which has imlib2 as a requirement.

        1 - Run make update from wm/enlightenment.
        2 - Wait for pkgsrc to start downloading the tarball for imlib2.
        3 - pkgsrc deletes the pkgs that require imlib2.
        4 - Before (maybe even while) the imlib2 tarball is downloaded,
             disconnect from the net.
        5 - Run `make update' again.
        6 - eterm is `forgotten', it is not reinstalled.
>Fix:
        No fix yet (I'm not very familiar with pkgsrc's inner workings)
