Description

To build documentation from Ubuntu, the installation instruction says

sudo apt-get install xsltproc zlib1g-dev

But I found that it didn't work for Ubuntu 14.04 as two packages, gem and ruby-dev are missed.

We should update the document to include both, i.e.

sudo apt-get install xsltproc zlib1g-dev gem ruby-dev
