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 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

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

As much as this might not be what you want to hear, I've always eventually given up on trying to use apt on ubuntu for ruby related stuff. Something funky's up with their debs.
Instead, I install ruby from source and then use the various scripts inside the source tarball to install almost everything else I need. It's much simpler in the long run, though you'll have to do upgrades by hand.
