Shouldn't you be able to omit the CHECK_INSTALL on this one?
The header files are not a runtime requirement, right?

Also wouldn't it be nicer to link this small library statically? This 
would omit the runtime requirement at all.
The test team just spelled yajl as "yet another library to get Xen 
running"...
Also be advised that it looks like this is relying on version 1 of yajl. 
It looks like the new version 2.0.1 is not compatible, I got compile 
errors with the newer version. If the stable version 1.x is required, 
this should be stated somewhere or at least checked properly in check_yajl.
Regards,
Andre.
