How to use roles in a Laravel package

I'd like to have roles in a package I'm creating. What is the best way to do this?

Should I use an existing package (Entrust, Bouncer, etc.) or should I implement a roles feature with no dependency?

Using an existing package could end in a conflict if it's already installed in another version, or if another package is already used.

Implementing the feature with no dependency is like reinventing the wheel...
