Eclipse question

[Hilly-Billy-13]

When I try to run Eclipse on the arduinoDuemilanoveCore I get the warning
Description Resource Path Location Type Invalid project path: Include path not found (\usr\avr\include). arduinoDuemilanoveCore pathentry Path Entry Problem

When I run Eclipse on the multiDisplay [Trunk/Eclipse/multidisplay] I get this warning
Description Resource Path Location Type Invalid project path: Include path not found (\usr\avr\include). multidisplay pathentry Path Entry Problem

Where both of these are referencing \usr\avr\include , do I need to add \usr\avr\include to my directories or should I ignore or comment out the line \usr\avr\include in the includes in both arduinoDuemilanoveCore and the MultiDisplay [Trunk/Eclipse/multidisplay]?
Thanks,
Bill
