These separate package managers might be a solution for development
outside of MacPorts. For ports depending on specific modules (for
example for software written in Ruby), we need to create ports in order
to specify this dependency and have it installed automatically.

I would also advise against providing multiple versions of mono as it
increases the required maintenance. As you noticed with the outdated
ports, we are already short on maintainers/contributors for mono ports.
