rvm and ruby for some beEF on OSX

There are many articles, some of them did not work for me and may not work for you… This is what I have made to succeed:

# uninstall all previous trials of rvm (modify .bash_profile and remove)
rm -rf .rvm*
# latest stable in my time was 2.0.0-p247
curl -L https://get.rvm.io | bash -s stable --ruby
# obviously this install does not modify profile
source ~/.rvm/scripts/rvm
# just looking
rvm list known
ruby --version
# switch from apples version ruby 1.8.7 to "latest"
rvm use ruby-2.0.0-p247
#
rvm gemset create beef
rvm use ruby-2.0.0-p247@beef
# swich to cloned source 
cd ~/beef/
# make ruby in this folder to be 2.0.0
echo 'rvm use ruby-2.0.0-p247@beef' > .rvmrc
# install
bundle install

# run
source ~/.rvm/scripts/rvm
rvmsudo ./beef
