Set macvim as default application after homebrew installation I've installed macvim via homebrew. This is working fine.

But when it commes to choose a default application for a new file type I cannot see MacVim. How can I set MacVim as the default application for a file type when it has been installed with homebrew?

Note: The question is not about how to select a default application in Finder, the question is how to set an application as default which is not listed in /Applications and there fore not shown by the Finder as a possible default application.
I had the same issue. I moved MacVim.app to /Applications and then symlinked it into the Homebrew cellar directory.

mv /usr/local/Cellar/macvim/7.3-65/MacVim.app /Applications/  
ln -s /Applications/MacVim.app /usr/local/Cellar/macvim/7.3-65/
