I followed the steps documented on under ‘installing from the distribution’:

  1. Launch
  2. gem install open4
  3. Copy to /Applications/*
  4. Copy the nub binary to /usr/local/bin (or somewhere else in your path).

However, when I navigate to a git repository and enter the nub command, the GitNub icon appears in my Dock for a second, and then silently disappears.

Any ideas?

Looks like active tickets for GitNub are here. These two bugs (one, two) describe the same symptoms. The second suggests a fix in the thread.

No Mac so I can't test; does either one look like your issue? Try running from Terminal to see any error messages.

Thanks, replacing NSMinYEdge by CGRectMinYEdge in /Applications/ (as in this commit:…) did the trick! – Mathias Bynens Jan 21 '10 at 11:30
