Growl notifier has been updated to 1.3.x last year, and it also became a paid software. Since it’s open-sourced, so I decided to build it myself. The steps are quite simple, just follow the documentation you will be fine. Just be sure you have mercurial (hg) command line tools.

A few things (or say, patches) are required to be made, some errors like ‘No newline at end of file’ are easy. I just post my patch which do some modifications here, please be noted that this may only apply to today’s Growl revision (hgRevision: 5809) with XCode 4.3 on Lion.

Core/Source/GroupController.m:

Core/Source/GrowlMenu.h:

After build success, open finder and drag the ‘Growl.app’ into Applications folder, run it. Growl!!
