Command line switch to say yes to dependencies?

[Sterling Smith]

Hi,

So it seems there is a new feature that asks if I want to install all of the dependencies of a requested port.  Is there a command line switch to answer yes?  If not, is there some other programmatic way to answer yes?  (This is installing for a non-default prefix from the master branch, so maybe there is something in master that hasn't made it to the documentation yet...)

Thanks,
Sterling
