Interesting. I create a jailed /dev with the following commands:
mount -t devfs devfs ${BASEDIR}/jail/dev
devfs rule -s 10 delset
devfs rule -s 10 add hide
devfs rule -s 10 add path null unhide
devfs rule -s 10 add path zero unhide
devfs rule -s 10 add path fd unhide
devfs rule -s 10 add path 'fd/*' unhide
devfs rule -s 10 add path 'std*' unhide
devfs -m ${BASEDIR}/jail/dev ruleset 10
devfs -m ${BASEDIR}/jail/dev rule applyset
and you've certainly got all of those devices.

I'm not sure why this would make any difference, but try
with just /dev/null, /dev/zero, /dev/fd, /dev/fd/*, and
/dev/std*.
Also, try listing the contents of /dev before starting
the buildworld, to make sure that nothing is missing.
