Could not load file or assembly PipelineHints


I built my solution in Release mode and deployed it, but it fails on my test machine. It can't find the PipelineHints assembly. According to the wiki documentation:
The attributes in this assembly are all marked with [ConditionalCompile("DEBUG")] so they will only show up in the debug builds of your contract assembly (builds with the "DEBUG" constant defined) and so your released code will have no dependence on the PipelineHints assembly or any other assemblies shipped in this project.
Am I doing something wrong? How can I deploy my solution without installing the PipelineHints assembly in the GAC?
