Title: no `recommended` or `optional` for dependencies

This formula's install method does not ensure `recommended` dependents will not be installed when `without` is specified for those dependents. The install method also does not ensure `optional` dependents are not installed when `with` is not specified for those dependents. Until that is provided, the dependents should not be neither `recommended` nor `optional`.
