Had this appear in a recent fresh install

==> Installing gng from gdubw/gng
Warning: gng: No available formula with the name "gdub". Did you mean gdu, gdb or dub?
'conflicts_with "gdub"' should be removed from gng.rb.
Please report this issue to the gdubw/homebrew-gng tap
 (not Homebrew/brew or Homebrew/homebrew-core)!

Reproduction was:

brew tap gdubw/gng
brew install gng
