Issue Installing on Raspberry Pi

I have been trying to get Dashing going on a Raspberry Pi but can't get past this issue.
sudo gem install dashing
Building native extensions.  This could take a while...
ERROR:  Error installing dashing:

To see why this extension failed to compile, please check the mkmf.log which can be found here:

/var/lib/gems/2.3.0/extensions/arm-linux/2.3.0/eventmachine-1.2.5/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.3.0/gems/eventmachine-1.2.5 for inspection.

Can someone please help?
