  2) Ensure that there is no 'return' from inside the ~/.bashrc file,
     otherwise rvm may be prevented from working properly.

     Be absolutely *sure* to REMOVE the '&& return'.

     If you wish to DRY up your config you can 'source ~/.bashrc' at the bottom of your .bash_profile.

     Placing all non-interactive (non login) items in the .bashrc,
     including the 'source' line above and any environment settings.

  3) CLOSE THIS SHELL and open a new one in order to use rvm.

Thank you very much for using RVM! I sincerely hope that RVM helps to
make your work both easier and more enjoyable.

If you have any questions, issues and/or ideas for improvement please
join#rvm on irc.freenode.net and let me know, note you must register
(http://bit.ly/5mGjlm) and identify (/msg nickserv <nick> <pass>) to
talk, this prevents spambots from ruining our day.

My irc nickname is 'wayneeseguin' and I hang out in #rvm typically

  ~09:00-17:00EDT and again from ~21:00EDT-~23:00EDT

If I do not respond right away, please hang around after asking your
question, I will respond as soon as I am back.  It is best to talk in
#rvm itself as then other users can help out should I be offline.

Be sure to get head often as rvm development happens fast,
you can do this by running 'rvm update --head' followed by 'rvm reload'
or opening a new shell

  w⦿‿⦿t

Upgrade Notes

  * Ruby package dependency list for your OS is given by:
    rvm notes

  * If you encounter any issues with a ruby 'X' your best bet is to:
    rvm remove X ; rvm install X

  * If you wish to have the 'pretty colors' again, set in ~/.rvmrc:
    export rvm_pretty_print_flag=1

  * If you see the following error message: Unknown alias name: 'default'
    re-set your default ruby, this is due to a change in how default works.
