Found this page, which pointed med to install ruby1.9.1-dev package.

Ok, trying again to install rmagick

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more

Found this question on superuser.com which pointed me to install the libmagickwand-dev-package.
sudo apt-get install libmagickwand-dev
Finally, another attempt to install rmagick
sudo gem install rmagick
