If you agree that this should be fixed in dwarves, I have a change viewable at http://repo.or.cz/w/dwarves/SamB.git?a=commitdiff;h=65d658b86413d10ffbb4a83a917af090d42df310which can be pulled from git://repo.or.cz/dwarves/SamB.git master which allows the configuration process to continue even if libebl is not found, on the assumption that the check_library_exists call will sort things out... hmm, looking at it again, I think I misunderstood the purpose of that call. Probably something like this can work, though... -- To unsubscribe from this list: send the line "unsubscribe dwarves" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
