Fix git-gui’s “Spell checking is unavailable” dialog

Unashamedly stolen from a Hints and Kinks blog post; I added information about the Homebrew solution

If you use ‘git gui’ on the Mac, you may find that it repeatedly pops up a message about spell checking being unavailable. This happens when using the MacPorts or Homebrew versions of git.

The error message will say something like (the language that’s missing might be different):

Spell checking is unavailable: No word lists can be found for the language “en_US”

You can easily fix this in MacPorts with:

sudo port install aspell aspell-dict-en

Or in Homebrew with:

brew install aspell --lang=en

Ciao!
