Bedrock Tutorial

On a base Gentoo system I have installed Bedrock and have started the tutorial.

brl list shows:
bedrock
gentoo
tut-alpine
tut-void

Following the tutorial I have run:

man jq | head | tee /tmp/tut1

in another terminal but get:

man: can't create temporary cat for /bedrock/cross/man/cat1/jq.1.gz: Function not implemented

brl which man gives me gentoo but the tutorial wants me to use Void's man command so I tried:

strat tut-void man jq

man: can't set the locale; make sure $LC_* and $LANG are correct
mandb: can't create index cache /bedrock/cross/man/19348: Function not implemented
man: can't create temporary cat for /bedrock/cross/man/cat1/jq.1.gz: Function not implemented

locale is:
LANG=en_GB.utf8
LC_CTYPE="en_GB.utf8"
LC_NUMERIC=POSIX
LC_TIME="en_GB.utf8"
LC_COLLATE="en_GB.utf8"
LC_MONETARY="en_GB.utf8"
LC_MESSAGES="en_GB.utf8"
LC_PAPER="en_GB.utf8"
LC_NAME="en_GB.utf8"
LC_ADDRESS="en_GB.utf8"
LC_TELEPHONE="en_GB.utf8"
LC_MEASUREMENT="en_GB.utf8"
LC_IDENTIFICATION="en_GB.utf8"
LC_ALL=

What do I need to do to sort this out so I can complete the tutorial please?
