You get this error because the development dependencies for Ruby are missing.
I suggest that you install and use RVM to solve this, check the official and updated instructions here https://rvm.io/rvm/install
At the time when I answer this question I followed these steps:
gpg --keyserver hkp://keys.gnupg.net --recv-keys
409B6B1796C275462A1703113804BB82D39DC0E3
\curl -sSL https://get.rvm.io | bash
If you get this warning
* WARNING: You have '~/.profile' file, you might want to load it,
to do that add the following line to '/home/mao/.bash_profile':
source ~/.profile
execute this command:
echo source ~/.profile >> ~/.bash_profile
Then, reload/apply the bash_profile that you just updated by executing this:
source ~/.bash_profile
Finally run this to install the requirements:
rvm requirements
This should work for any Linux distribution like Ubuntu, Fedora, Debian, Redhat, Slackware.

You seem to be missing some Ruby requirement. If you are using RVM, try:
rvm requirements
to get the list of dependencies and install them manually.
Otherwise, install the known basic requirements directly using:
sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libxml2-dev autoconf libc6-dev ncurses-dev automake libtool

After upgrading to Rails 4.2.4 on Ubuntu 14.04 using RVM I needed to do this:
sudo apt-get install libgmp-dev
or
sudo apt-get install libgmp3-dev
