rbenv rails 4 on 3.10 manjaro

After I have changed my debian server from rvm to use rbenv I gave it a shot for my local system:

These commands should work:

1. git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
2. echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
3. echo 'eval "$(rbenv init -)"' >> ~/.bashrc
4. "type rbenv" should show something like "rbenv is a function"
5. git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
6. git clone https://github.com/sstephenson/rbenv-gem-rehash.git ~/.rbenv/plugins/rbenv-gem-rehash
7. rbenv install 2.1.1 -k
8. rbenv global 2.1.1
9. gem install rails
 

But unfortunately first ruby and then rails were not working as good on manjaro/arch as on debian. So I had to find solutions:

1. CONFIGURE_OPTS="--with-readline-dir=/usr/include/readline" rbenv install 2.1.1
   OR (could not get console working, tried following)
   curl -fsSL https://gist.github.com/mislav/a18b9d7f0dc5b9efc162.txt | rbenv install --patch 2.1.1
   (source)
2. gem install railties && rbenv rehash 

And now I am happy!
