Several months ago I asked about a feature that would always force
DEPENDS. For example, I wanted to make sure my packages were built knowing
what there dependencies were, like openssh package should depend on
openssl (even if openssl was already installed in my LOCALBASE as /usr).

I'd like a variable, maybe called PREFER_PKGSRC, that would be used for:

- any time a buildlink is used, then skip any checks for native versions
  of the installed software -- and always use the pkgsrc equivalent;

- then would always set up the DEPENDS (@pkgdep and +REQUIRED_BY)
  correctly.

This would be useful for a few reasons:

- ignore possibly insecure or out-of-date native software;

- later can remove native software that is out-of-date or insecure
  (without breaking pkgsrc that may depend on it);

- known behaviour;

- any dependency checks looking in LOCALBASE (i.e. /usr) will be
  registered (+REQUIRED_BY for example).

Any thoughts?

Can this already be done?
