What if two modules have the same name?

I have two packages that provide modules with the same name. When I try to load a module, I get an error

An ambiguous interface for ....: It has been found in several packages.

What to do to resolve this?

To be specific, package cryptoniteand crypto-apiprovide modules named Crypto.Random. How can I indicate which package I want to load from a module?
