Ubuntu has a libcdk5 package. Are you sure that Arch does not have it? 
Because there is perl and java bindings too.

The Highlight class is in the gb.eval component. It is extended into the 
gb.qt4.ext editor so that you can add custom highlighting to the Editor 
through a "Highlight" event that is called for each editor line that 
must be highlighted.

This feature is used by the gb.eval.highlight component that implements 
highlighting for some text formats (html, C, javascript, css...).
