Git OS X Installer
Patches (see the README_PATCHES.txt file) to build a version of Git for Mac OS X 10.4.8 and later (PPC/X86/32/64) that includes the Git translations (optionally selected based on System Preferences > International > Languages) and integrates well with the native OS X libraries.
The built version of Git uses Secure Transport (via a very enhanced version of curl's darwinssl backend) to fully support SHA-256 https certificates on Mac OS X 10.4 and Mac OS X 10.5 without need for a custom build of OpenSSL.
All certificates for https/smtps/imaps verification come from the standard system keychain locations (unless one of the Git certificate configuration options is used).
Patches are also included to allow GnuPG to generate larger RSA keys (again, see README_PATCHES.txt for details).
Pre-built installers that include Git, TopGit (optional), the curl comand line utility (optional) and GnuPG (optional) can be found on the Git OS X Installer home page.
