mattmanning / heroku-buildpack-ruby-jekyll Goto Github PK

I'm seeing this output when I try to push to Heroku today. (I wasn't getting this problem last time I pushed, about three days ago.)

My heroku:config includes this line:

BUILDPACK_URL: http://github.com/mattmanning/heroku-buildpack-ruby-jekyll.git

If I remove that (heroku config:remove BUILDPACK_URL), I can push with no issues. So I suspect it's something to do with the changes made in the last few days - though looking over them, I'm not sure what it could be. Any ideas?

The jekyll build command in /lib/language_pack/ruby.rb on line 600 is depreciated.
It needs to be updated to work with the new syntax of Jekyll.
