went to build a kernel

    >>> stage 1: configuring the kernel
    --------------------------------------------------------------
    cd /usr/src/sys/i386/conf;  PATH=/usr/obj/usr/src/i386/legacy/usr/sbin:/usr/obj/usr/src/i386/legacy/usr/bin:/usr/obj/usr/src/i386/legacy/usr/games:/usr/obj/usr/src/i386/usr/sbin:/usr/obj/usr/src/i386/usr/bin:/usr/obj/usr/src/i386/usr/games:/sbin:/bin:/usr/sbin:/usr/bin  config  -d /usr/obj/usr/src/sys/RAN  /usr/src/sys/i386/conf/RAN
    ERROR: version of config(8) does not match kernel!
    config version = 500012, version required = 500013

    Make sure that /usr/src/usr.sbin/config is in sync
    with your /usr/src/sys and install a new config binary
    before trying this again.

    If running the new config fails check your config
    file against the GENERIC or LINT config files for
    changes in config syntax, or option/device naming
    conventions

    *** Error code 1

    Stop in /usr/src.
    *** Error code 1

perhaps UPDATING needs to note that one needs to

   cd /usr/src/usr.sbin/config
   make install

if one is building recently?  or am i missing something more
basic here?
