FATAL command "build" failed: failed to resolve import path "cmd": no buildable Go source files in /home/dfc/go/src/cmd

Blocked by #306

[davecheney]

FWIW, this is not a high priority item, although #306 is on the roadmap.

Even if this was possible, building this package would result in a binary $PROJECT/bin/cmd, which is questionably named, at best.
