We've switched to git
almost entirely. After running into some rather painful overhead with getting everyone on Git (especially our designers, who generally don't have Developer Tools installed already), I set out to create an installer. Here are the fruits of that endeavor:
Download Git for OS X
It's worked well on several Leopard machines. It ships with it's dependencies, and will handle updating your environment variables in
~/.bash_profile for you. Isn't that nice? Everything is installed cleanly into the directory /usr/local/git, so removal is easy. See, git is your friend now.
If you've got another installation of Git, you may want to remove it first before switching over to the package distribution
Want to build your own package for Git and OSX? Head on over here, for the source and instructions used to create the package.
Update: The original release was 40MB and took up 85MB of hard disk space! After some optimization tips from Pieter and Johannes Schindelin, it's now weighing in at 3.2MB download, ~8MB installation size. Much better!
