I have decided to give rbenv a go instead of rvm. I have installed it with Homebrew which was straight forward. I then added the extra lines to my .bash_profile like so (shims, autocompletion and eval statement).
export PATH="/usr/local/bin:/usr/local/mysql/bin:~/.rbenv/shims:~/.rbenv/completions/rbenv.bash:$PATH"
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
Then after restating terminal I have tried to run it ie,
lee$ rbenv version
system (set by /Users/lee/.rbenv/version)
lee$ rbenv versions
lee$
As you can see Im getting no versions and no current version.
Is there something I missed ?
