Warning, because of factory_girl gem module, ruby9 is mandatory

aptitude install rubygems1.9.1 ruby1.9.1-dev libpq-dev libxml2-dev libxslt1-dev postgresql // probably others

git clone --depth=1 git://github.com/rapid7/metasploit-framework metasploit
cd metasploit
gem install bundle
bundle install

postgresql is not mandatory, it's used to speed up "search".
