KERNEL_INCLUDE should point to correct linux kernel include directory.
Default (/usr/src/linux/include) is right as rule.
+arpd needs to have the db4 development libraries. For debian
+users this is the package with a name like libdb4.x-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkely
database routines. Often this is in the db-devel package.
