There's no way for your package to tell R to ignore the dependencies
declared by foo_depend.
If you really only need one function from that package, simply copy the
source of miscFUN into your package (assuming foo_depend's license
permits that). But this is not best practice, unless that function is
very simple. Best practice is to declare your dependence by importing
that function from foo_depend.
