Hello @nordicdyno!
Can you tell me what version (I mean the commit hash) of codegangsta/cli have you installed?
Aliases were added in urfave/cli@bf65971.

If you can't update codegangsta/cli in your usual GOPATH env, you can try the following:

% cd /path/to/somewhere
% env GOPATH=`pwd` go get eriol.xyz/piken

If this works, you will find piken command inside /path/to/somewhere/bin directory.

I'm thinking about to start managing dependencies in a better way, sorry for the annoyance related to not having versioned dependencies.
