I’ve been looking at git for source control, and put together a Mac OS X package installer that will install a Universal binary of git and its man pages into
/usr/local. The pax archive in pkg files seems to seriously expand the size — 30M of program files make for a >100M installer!
I’ve only tried this on Intel Macs, so your mileage may vary.
Update: See the newest version.
Update: Also give the torrent a try: git-18.104.22.168.pkg.zip.torrent
Edit: this page will hold further updates for this package.
