Should mason install deps?

[mikemorris]

Currently mason doesn't install dependencies for mesa-10.3.1, only installing them on Travis. Should dependencies be checked/installed when a mason package is installed?

Hmm, how do you install without being sudo on Linux?

Perhaps just spit out a nice message:
"Cannot install mesa-10.3.1 due to missing system dependencies.

Please run 'sudo apt-get install blah'."

[mikemorris]

Hmm, yea hadn't considered that but we definitely need to take that into account @ljbade

Stale. Mason does not currently have support for installing runtime deps. The latest mesa package attempts to statically link as much as possible therefore: #324
