I am running Debian so I need the libreadline5-dev package to get the
libreadline.so and readline headers.

The gem installs both with and without this package installed (the
versioned readline shared library is always installed as dependecy of
many packages).

When the gem is installed without the readline development package
present it installs successfully without any error reported but the
extension fails to load when used by ripl.
