Answer 1

When asking a question is often helps to explain what the software is good for and how to reproduce the problem. This is not a juicer or ruby forum and there are probably not many if any user familiar with juicer in this forum. But for what it's worth, the following works in Oracle Linux 6.3 x86 and probably other release versions:
curl -L https://get.rvm.io | bash -s stable --ruby
source /usr/local/rvm/scripts/rvm
ruby --version
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
gem install --verbose juicer
juicer --version
juicer 1.1.1
juicer help
Usage: juicer [global options] COMMAND [options] [ARGS]
Available commands:
    help            Provide help for individual commands
    install         Install a third party library
    list            Lists all dependencies for all input files/patterns
    merge           Combines and minifies CSS and JavaScript files
    verify          Verifies that the given JavaScript/CSS file is problem free
    version         Show the version of the program
Global options:
    -v, --verbose                    Be verbose when outputting info
    -q, --quiet                      Only log warnings and errors
    -h, --help                       Show help
        --version                    Show the version of the program
P.S. nokogiri requires Ruby version >= 1.9.2.
