Subject: Re: ruby 1.9 side by side with 1.8

I solved it with this lines in .bashrc:

alias ruby-switch-18='sudo ln -fs /usr/bin/ruby1.8 /usr/local/bin/ruby
&&
  sudo ln -fs /usr/bin/irb1.8 /usr/local/bin/irb &&
  sudo ln -fs /usr/bin/gem1.8 /usr/local/bin/gem' &&
  sudo ln -fs /usr/bin/rake /usr/local/bin/rake'

alias ruby-switch-19='sudo ln -fs ~/.ruby_versions/ruby-1.9.1-p129/bin/
ruby /usr/local/bin/ruby &&
  sudo ln -fs ~/.ruby_versions/ruby-1.9.1-p129/bin/irb /usr/local/bin/
irb &&
  sudo ln -fs ~/.ruby_versions/ruby-1.9.1-p129/bin/gem /usr/local/bin/
gem'&&
  sudo ln -fs ~/.ruby_versions/ruby-1.9.1-p129/bin/rake /usr/local/bin/
rake'


now i still have issue when running rake gems:install
rake aborted!
