`detect_latest_version': uninitialized constant Object::Octokit (NameError)

[okamuuu]

Hi, I found an error, so I'm reporting.

here is my .buildpacks

% cat .buildpacks
https://github.com/groonga/heroku-buildpack-groonga.git
https://github.com/heroku/heroku-buildpack-nodejs.git

in this case, it looks to occurr error.

% git push heroku master
...
-----> Fetching custom git buildpack... done
-----> Multipack app detected
=====> Downloading Buildpack: https://github.com/groonga/heroku-buildpack-groonga.git
=====> Detected Framework: Groonga
/tmp/buildpackvO3Fm/bin/compile:14:in `detect_latest_version': uninitialized constant Object::Octokit (NameError)
        from /tmp/buildpackvO3Fm/bin/compile:72:in `<main>'
-----> Loading environment variables

 !     Push rejected, failed to compile Multipack app

so I have to set config like this to avoid to call detect_latest_version.

% heroku config:set GROONGA_VERSION=4.0.4
