Hi,

I released rcairo(*1) 1.8.5 that fixes build related
problems in 1.8.3+
 http://raa.ruby-lang.org/project/rcairo/

(*1) A library to use cairo(*2) from Ruby.

(*2) A 2D graphics library that is used by
     GTK+/Firefox/WebKit/... as rendering backend and worked
     on multi-platform. cairo can output PDF, PNG, SVG and
     so on too.
