So you just installed Growl, eh? Wait! Before you unmount that .dmg, don’t forget to install growlnotify from the Extras directory.
cd /Volumes/Growl/Extras/growlnotify
sudo install.sh
If you get a permission denied error you might also need to do this:
sudo ln -s /usr/local/share/man /usr/local/man
Ok but why am I doing all of this? Check it out:
growlnotify --appIcon Xcode
-m "growlnotify has finished building" Build Complete
Cool!
