I'm attempting to build a custom kernel, but when it comes time to build, it fails with this error: /usr/src/sys/dev/re/if_re.c:151:23: miibus_if.h: No such file or directory /usr/src/sys/pci/if_rl.c:125:23: miibus_if.h: No such file or directory mkdep: compile failed *** Error code 1 It may be a simple problem, but I'm lost.
