Out of the box, Quicksilver, a wonderful app launcher and more for Mac, and Subversion, a top open source version control system do not have a happy marriage. The Subversion plug-in for Quicksilver is expecting the svn binary to be /usr/local/bin/svn, but it is not, it can be found at /usr/bin/svn. However, a simple change can make all well in the world again, fixing the broken marriage of Quicksilver and Subversion.
1. Open a Terminal and type
[sh]defaults write com.blacktree.Quicksilver QSSVNPluginSVNPATH /usr/bin/svn[/sh]
2. Quit Quicksilver and relaunch it
3. Control+Space to launch Quicksilver
4. Type a Subversion controlled filename
5. Execute the SVN Log action
6. Jump for joy!!
Hopefully this helped you get your local development environment humming without using that silly little mouse.
