I am working on getting my development environment setup on my new mac, and ran into an under-documented error: “could not find any SCM named `git’”.
It turns out that Leopard installs capistrano 2.0 automatically, and in a battle between /usr/bin/ and /opt/local/bin, the first one on the path of course wins. The trick is to run sudo /usr/bin/gem uninstall capistrano which will get rid of both the gem, and more importantly the cap and capify commands that came with it. Now just install capistrano in your macports install of gems sudo /opt/local/bin/gem install capistrano and run cap: /opt/local/bin/cap deploy
This blog post was very helpful while I was hunting down this info.
