Why is Git not found after installing OS X Lion? I just upgraded to OS X Lion and now cannot initialize Git where it used to work fine:

$ git add .

-bash: git: command not found


I'm new to Git and to programming, so I'm sure it's a quick fix, any help is greatly appreciated.  Thanks guys!
If /usr/local/git already exists, you'll need to either add it to your $PATH or make a symlink placing the symlink inside a directory that is in your existing PATH.

A common practice is to make /usr/local/bin if it doesn't exist and add a link:

sudo -s
mkdir -p /usr/local/bin
ln -s /usr/local/git/bin/git /usr/local/bin/git
exit
