Что еще я могу попробовать?
user15:~ durrantm$ bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
user15:~ durrantm$ cat .bash_profile
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function
user15:~ durrantm$ type rvm | head -n1
-bash: type: rvm: not found
user15:~ durrantm$ rvm -v
-bash: rvm: command not found
user15:~ durrantm$
Также это не помогло ...
sudo gem install rvm -s http://gemcutter.org/
