issue #90 reanimated as zombie to eat my brains

[sunaku]

The error described in issue #90 has reappeared in my bundler environment, but does not occur outside of it. I am including the exact gem versions from both cases in this report, below, for your debugging pleasure.

My current workaround is the following monkeypatch: ✨

if defined? Rake::DeprecatedObjectDSL
  Rake::DeprecatedObjectDSL.module_eval do
    undef symlink
    undef install # for bundler/capistrano
  end
end

Thanks for your consideration.
