Error installing Mix IDE

[ksank1976]

I am getting the below error when trying to install the Mix IDE for Ethereum.
"No Such file or Directory". Appreciate your help in resolving the error.

When you exit this IRB session, execution will continue.

Please could you re-file this against http://github.com/ethereum/mix?
This issue tracker is for the Ethereum Wiki. Thanks!

PS. Also best to put the logs into a gist.github.com file and link, so the formatting doesn't go weird.
