Er, sorry for the ignorance: if my model name is "r_10gbe" and block name is "gbe0" than is my complete block a combination of those? (or does it include hard drive path, etc.) I tried grepping through my r_10gbe/ compilation directory for clues... Or is it a function of the block library, e.g., "xps_library/ten_Gbe"? I was wondering if my yellow 10gbe blocks are too "new" for my older configuration, but they are dated before the 10gbe tutorial files. Maybe I'll just bite the bullet and see if upgrading my configuration at least gets the (newer) tutorial to work ...
