Yeah, we had the same problem in PEAR. And that is why we added set_include_path to make it possible for people to keep their own little repository of PEAR apps and still ensuring that they don't use different relative include paths. I was really not happy with the solution at the time. Because that means that I either have to fix all the PEAR apps that I bundle with my application to not use the expensive include_path or accept the performance hit. Regards, Lukas
