title: Brew Install Python Fails Due to Link gdbm link issue
body: <p>I am used to macport and recently got a new mac book pro 10.8.4, and I switched <code>brew</code> and tried to install python but I am getting following error:</p>
  
  <pre><code>brew install python --universal --framework
  Error: You must `brew link gdbm' before python can be installed
  </code></pre>
  
  <p>I tried to follow following links to install python using brew but it was keep saying about link, which I don't understand.

  <p>Here are the warnings that I get:</p>
  
  <pre><code> brew install readline sqlite gdbm
  Warning: readline-6.2.4 already installed
  Warning: sqlite-3.7.17 already installed
  Warning: gdbm-1.10 already installed, it's just not linked
  </code></pre>
  
  <p>In addition to this I have tried to link it brew link gdbm but I get the following permission issue:</p>
  
  <pre><code>file: /usr/local/Cellar/gdbm/1.10/include/gdbm.h
  /usr/local/include is not writable. You should change its permissions.
  </code></pre>
  
  <p>I check the /usr/local/include and it has a write permission</p>
  
  <pre><code>drwxr-xr-x  29 root      wheel    986 Mar 30 16:46 include ( I am not the root) 
  </code></pre>
  
  <p>I am not the root and don't have the root password, but I do have sudo rights on the machine.</p>
