Of course this file exists but .exists() returns false,
this is exactly what i'm talking about.

To find a problem

0 xxkb>ktrace make show-var VARNAME=SU_CMD 
/usr/bin/su - root -c
0 xxkb>kdump | grep -C1 /bin/sudo
        #
        .if exists(${LOCALBASE}/bin/sudo)
        SU_CMD=         ${LOCALBASE}/bin/sudo /bin/sh -c
        .endif

Of course, /bin/sudo doesn't exist.
Something is wrong with '.if exists(${LOCALBASE}/bin/sudo)',
variable LOCALBASE is expanded incorrectly.
I'm not expert in BSD make,
but this variable is probably substituted before
it is initialized in mk/defaults/mk.conf.

And doesn't for me. See above.

Each time I run pkg_chk or something similar I should remember that
sudo is installed?  No, thanks, I better copy sudo to /usr/local just
like my favourite shell to /bin
