Creating group 'rvm'
 
Installing RVM to /usr/local/rvm/
cp: cannot stat `/usr/local/rvm/src/rvm/bin/rake': No such file or directory
cp: cannot stat `/usr/local/rvm/src/rvm/bin/bundle': No such file or directory
Installation of RVM in /usr/local/rvm/ is almost complete:
 
  * First you need to add all users that will be using rvm to 'rvm' group,
    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.
 
  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
    in all your open shell windows, in rare cases you need to reopen all shell windows.
 
# Administrator,
#
#   Thank you for using RVM!
#   We sincerely hope that RVM helps to make your life easier and more enjoyable!!!
#
# ~Wayne, Michal & team.
