ruby-vcr: DFSG violation (Hippocratic license)

[Pirate Praveen]

It looks like we will have to remove ruby-vcr and we will have to 
disable tests for the following packages. I don't think there is 
another way, thoughts?

No reverse dependencies.
reverse-depends -b ruby-vcr

* nanoc
* ruby-coveralls
* ruby-graphlient
* ruby-mixlib-install
* ruby-octokit
