# The main issues with Ruby 1.8.7 are that it won't build with Clang,
# and the Net::HTTPS module won't work with modern versions of OpenSSL.
#
# This assumes you have already set up homebrew, and run: xcode-select --install

#brew install homebrew/dupes/apple-gcc42
#brew install libyaml libffi

# Important gems:
# Rake is not installed by default, but you should start with a very old version before installing 10+:
gem install rake -v 0.7.3 # needed for very old Rails sites and some old gems to install
gem install slimgems # needed for Rails 1 + 2 to install

# if you want the latest rdoc for 1.8:
gem install rdoc -v 3.12.2
gem install rdoc-data -v 3.12
rdoc-data --install

# as of this writing, the latest version of bundler, 1.14.5, was still backwards compatible with Ruby 1.8
gem install bundler
