The documentation doesn't say one way or the other. But the fact remains
that base:::.getRequiredPackages2, when provided a non-null lib.loc,
uses that lib.loc when checking versions of dependencies. So (to me) it
seems a little incongruous that base:::.getRequiredPackages2 offers this
functionality but library() doesn't take advantage of it. Moreover, it
is already passing the 'quietly' argument...

Agreed, in which case I would explicitly load the dependency first
specifying a custom lib.loc.
