I am trying to follow this guide: https://github.com/ic0nic/The-Four-L...igs-Siri-Proxy to install my SiriProxy. I have ran into a problem. I run this command:

rvmsudo gem update

and I get the following error returned:

/usr/bin/env: gem: No such file or directory

I do have everything installed, so why can I not run this command?
