# ERROR: This package must be compiled with GCC, but ruby-build couldn't
# find a suitable `gcc` executable on your system. Please install GCC
# and try again.
# This will fix it:

brew tap homebrew/dupes
brew install apple-gcc42

# * installs your desired ruby versions using rbenv
# ** including openssl (needed by bundler)
# ** including sqlite (probably needed for rails apps)
#
# Before you start:
# * put ssh-keys in place
# * $ ssh git@github.com
# * If you're behind a proxy, be sure to set $http_proxy etc!
#
# After the Script has run:
# * reload your .bash_profile
