# i've tried varieties of rvm install in fail, 
# also, I didnt think about not needing to run it as root. 
# When you install it, you don't have to be root.

# this seems to work 

# just copy and paste this bit:

RVM_GIT_REPO=git://github.com/wayneeseguin/rvm.git
mkdir -p $HOME/.rvm/src && cd $HOME/.rvm/src && 
git clone --depth 1 ${RVM_GIT_REPO} && 
cd rvm && 
./install

# then add this last bit to the bottom your /etc/profile
# by running :

sudo echo 'if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then source "$HOME/.rvm/scripts/rvm" ; fi' >> /etc/profile

# all done

exit your terminal 

open terminal 

rvm list known

# this works, will used latest
rvm install 1.8.6
# start using it
rvm use 1.8.6

rvm default ruby-1.8.6-p399
