LOCALBASE is used in various other non-ports Makefiles to find things installed by ports/packages. There is in fact another variable I failed to mention (LOCAL_MODULES_DIR which defaults to LOCALBASE/sys/modules) and one could set that instead of LOCALBASE for the /mnt case. >>> How about when I'm doing a build of 11-stable for testing, but what's >>> in my /usr/local is sources for a 13-current driver? >> Given that the kmod's are supposed to be portable across branches, >> the build really shouldn't be breaking.

As I said, you can set LOCAL_MODULES="" in /etc/src.conf if you want a global knob, or you can set it with smaller granularity in either a kernel config or on the command line. -- John Baldwin
