One use case I can think of is if you want to use the same packaged versions between the developer machine (OSX) and your deployment environment (Linux). It not 100% the same but it could help uncover issues before they are deployed. And you don't get the overhead of visualization.

You get exactly the same with macports and brew: Very little patching and no virtualization.

The package definition is not the same or are you using brew and macports to install on Linux ?
