title: exec format error
body: <p>I recently installed lubuntu 11.04 on my pc. Following <a href="http://golang.org/doc/install/source" rel="noreferrer">this guide</a> on installing go from source, installing golang on my pc went well. To test my installation, I ran hello.go and got this error:</p>
  
  <pre><code>fork/exec /tmp/go-build748212890/command-line-arguments/_obj/a.out: exec format error
  </code></pre>
  
  <p>I looked it up on google, and one of the more relevant results that I found said to remove the package, then reinstall again. That did not help.</p>
  
  <p>Can you tell me what is causing this error, and how I can fix this?</p>
  
  <p>Thanks, and have a nice day!</p>
