Unable to install latest version 2.12.0 on Ubuntu 14.04

I'm unable to install the latest version of puma on an Ubuntu 14.04 VirtualBox VM. I get the following error:

vagrant@default-ubuntu-1404:~$ sudo gem install puma
Building native extensions.  This could take a while...
ERROR:  Error installing puma:

I am using Chef and the community puma cookbook to bootstrap my node, and everything works fine when I lock the puma version to 2.11.2. Anyone have any thoughts?

+1 any workaround?

It is probably due to strict compiler flags used in most of new linux distros.

Thanks for quick solution.
