Havana Install Guide

Same setup procedure of Trema Sliceable Switch.

Ubuntu 12.04 LTS

Install dependency packages

Although Trema website says ruby 1.8 should be installed, I cannot install some dependency ruby module with ruby 1.8.7. https://github.com/trema/trema/issues/340 (Cannot run trema on Ubuntu 12.04 and ruby 1.8.7)

It seems good with Ruby 1.9.1.

sudo aptitude install gcc make ruby1.9.1 rubygems ruby1.9.1-dev ¥
    libpcap-dev libsqlite3-dev libglib2.0-dev sqlite3 libdbi-perl ¥
    libdbd-sqlite3-perl apache2 libjson-perl
sudo gem1.9.1 install trema
sudo bundle install
