Problems installing Ruby gem "ffi" on Ubuntu Server 12.04

I'm trying to use bundle to install gems required for my new project, but I'm having trouble installing version 1.1.5 of the 'ffi' gem.

I'm using Ruby 1.9.3 running on a virtualised install of 64-bit Ubuntu Server 12.04. When running the bundle command, I receive the following error message:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing ffi (1.1.5), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.1.5'` succeeds before bundling.

The error seems to be caused by the line make[3]: *** No rule to make target 'ffi.3', needed by 'all-am' but I'm none the wiser as to what this means.

Can anybody help me out? Thanks in advance!

Install the libffi-dev package:

sudo apt-get install libffi-dev

The ffi gem will build its internal libffi library if it cannot find the headers/link lib for libffi, which on a modern linux system is never what you want - just install your system's dev packages.
