Are you asking what happens if a CRAN package depends on a BioC package which is missing from BioC?

You can safely assume the availability of BioC and Ohat packages (provided we can install these). We do not accept packages with unconditional (depends/imports) dependencies on package not in the standard repositories, but do not force the availability of suggested packages: so you can suggest an external package (but R CMD check should still pass if the package is not available).
