Hi Folks,
here all the tools you need as of today (Sept. 26th, 2013) for building growl (or other projects) from the sources. works ON MOUNTAIN LION.
I included everything, just to provide downloads, without having to create a developer ID.
This is a public repo, and since I don't know about security on git:
SCAN THESE FILES FOR VIRUSES. CHECK CRC/MD5
You have been warned. cheerio, erdnuesse
