[Distutils] Buildout question

[Scott Robertson]

Thanks Jim,
I stumbled upon that myself this  weekend wasn't sure if it was appropriate.

 One thing I noticed, is that if you use the "install" keyword on the
command line i.e.
$ buildout install some-section

Dependent sections don't get built (is that intentional?)

This patch seems to do the trick, though I'm not sure if it causes any
unindented side effects.
