title: Fail to install Go 1.2.1 in Mac OS X Mavericks
body: <p>I followed the <a href="https://code.google.com/p/go/downloads/detail?name=go1.2.1.darwin-amd64-osx10.8.pkg&amp;can=2&amp;q=" rel="nofollow">link</a> to download Go 1.2.1 and tried to install in Mavericks OSX. After installing with the binary package, I cd into the path /usr/local/go and found all the executables. However when I try to run</p>
  
  <pre><code>go version
  </code></pre>
  
  <p>it returns</p>
  
  <pre><code>$ command not found: go
  </code></pre>
  
  <p>I am not sure what I did wrong but I can't find any resource to it. I also tried to follow this tutorial (<a href="http://www.raulmurciano.com/articles/setting-up-go-for-development/" rel="nofollow">link</a>) but still failed. Any help?</p>
