You need a full Ruby installation, from the path "/var/lib" looks like
you're running Ubuntu.

Please install ruby-dev package and try again.

Also, you need mysql and libmysql-dev packages to compile.

I've been scratching my head all afternoon as you suggested sudo apt-
get install ruby-dev and then running sudo gem install mysql worked
sort of I got a whole lot of definition errors but I'm closer than I
was

I was getting the exact same error - I can get sudo gem install mysql
to load only after running sudo apt-get install ruby-dev but then
rails app reports wrong wrong gem version and asks me to 2.2.3 back
from 2.2.5 sudo gem install -v=2.2.3 rails run app and web brick
starts and displays default page go to generators scaffold works then
rake db migrate you should get a password error alter user name and
password for all environments and I am hoping that works
