For experimental users.

Download rcairo-X.Y.Z.tar.gz from cairographics.org/releases/

Extracting:

    % tar xvzf rcairo-X.Y.Z.tar.gz

Compiling:

    % cd rcairo-X.Y.Z
    % ruby extconf.rb    # to check for dependencies and create Makefiles
    % make               # to compile

    # make install       # to install the cairo extension.
                         # The samples in the samples folder should be able
                         # to run before installation except text-on-path.rb
                         # and text2.rb. They uses Ruby/Pango with rcairo
                         # support. So you need to install rcairo and build
                         # Ruby/Pango with it before you run them.

    * --without-vendor-override: Use system libraries instead of those found in
                                 vendor/local for compiling
