title: ec2_bundle_vol fails with error LoadError
body: <p>I am a newbie in amazon ec2 setup.</p>
  
  <p>I have now setup a machine to my taste - and I now want to bundle it.</p>
  
  <p>I am running the following command from the launched instance -</p>
  
  <pre><code>root@domU-21-34-67-26-ED-Z4:~# ec2-bundle-vol -r i386 -d /mnt \
                                -p ACT-VOL -u 8940-1355-4155 -k /tmp/pk-key.pem \
                                -c /tmp/cert.pem -s 10240 \
                                -e /mnt,/root/.ssh,/home/ubuntu/.ssh
  
  ruby: No such file or directory -- 
   /home/ubuntu/ec2tools/ec2-api-tools-1.3-46266/lib/ec2/amitools/bundlevol.rb (LoadError)
  </code></pre>
  
  <p>The ruby version is 1.8.7. I searched internet and installed libruby1.8-extras etc too,  but to no avail. I also tried running it from site_ruby (/usr/local/lib/site_ruby) - but no use.</p>
  
  <p>I tried installing 1.8.6 version of ruby, but was unable to find a way to do so too.</p>
  
  <p>Any help would be much appreciated.</p>
  
  <p>Thanks,
  K</p>
  
  <p>EDIT: One more question is : Should I be running this command in my local machine or should I run this command in the launched instance?</p>
