title: Error: The 'brew link' step did not complete successfully
body: <p>I'm trying to install node.js via Homebrew. Unfortunately, I get this error:</p>
  
  <pre><code>➜  ~  brew install node
  ==&gt; Downloading http://nodejs.org/dist/v0.8.10/node-v0.8.10.tar.gz
  ######################################################################## 100.0%
  ==&gt; ./configure --prefix=/usr/local/Cellar/node/0.8.10
  ==&gt; make install
  ==&gt; Caveats
  Homebrew installed npm.
  We recommend prepending the following path to your PATH environment
  variable to have npm-installed binaries picked up:
    /usr/local/share/npm/bin
  Warning: Could not link node. Unlinking...
  Error: The `brew link` step did not complete successfully
  The formula built, but is not symlinked into /usr/local
  You can try again using `brew link node'
  ==&gt; Summary
  /usr/local/Cellar/node/0.8.10: 856 files, 13M, built in 103 seconds
  </code></pre>
  
  <p>So then I try to link node manually...</p>
  
  <pre><code>➜  ~  brew link node
  Linking /usr/local/Cellar/node/0.8.10... Warning: Could not link node. Unlinking...
  
  Error: Could not symlink file: /usr/local/Cellar/node/0.8.10/lib/node_modules/npm/scripts/relocate.sh
  Target /usr/local/lib/node_modules/npm/scripts/relocate.sh already exists. You may need to delete it.
  To force the link and delete this file, do:
    brew link -f formula_name
  
  To list all files that would be deleted:
    brew link -n formula_name
  </code></pre>
  
  <p>No luck, so I try forcefully linking node...</p>
  
  <pre><code>➜  ~  brew link -f node
  Linking /usr/local/Cellar/node/0.8.10... Warning: Could not link node. Unlinking...
  
  Error: Permission denied - /usr/local/lib/dtrace/node.d
  </code></pre>
  
  <p>I'm not familiar with dtrace in any regard and I'm afraid to mess with permissions, so I tried to sudo..</p>
  
  <pre><code>➜ ~ git:(master) sudo brew link -f node
  Password:
  Error: Cowardly refusing to `sudo brew link'
  You can use brew with sudo, but only if the brew executable is owned by root.
  However, this is both not recommended and completely unsupported so do so at
  your own risk.
  </code></pre>
  
  <p>I've tried uninstalling node via <code>brew uninstall node</code> and retrying the install with no luck.</p>
