Doesn't seem to work:

   # grep -E '^(LANG|LC_|L10)' /etc/portage/make.conf
   L10N="en-GB"
   LANG="en_GB"
   LC_MESSAGES="C"
   # env | grep -E '^(LANG|LC_|L10)'
   LANG=en_GB.utf8
   LANGUAGE=en_GB:en_US:en
   LC_ADDRESS=en_GB.UTF-8
   LC_COLLATE=C
   LC_IDENTIFICATION=en_GB.UTF-8
   LC_MEASUREMENT=en_GB.UTF-8
   LC_MONETARY=en_GB.UTF-8
   LC_NAME=en_GB.UTF-8
   LC_NUMERIC=en_GB.UTF-8
   LC_PAPER=en_GB.UTF-8
   LC_TELEPHONE=en_GB.UTF-8
   LC_TIME=en_GB.UTF-8
   # locale -a
   C
   C.utf8
   POSIX
   en_GB.utf8
   # localedef --list-archive
   C.utf8
   en_GB.utf8
   # emerge --ask --changed-deps --deep --newuse --update \
     --verbose-conflicts --with-bdeps=y @world

   These are the packages that would be merged, in order:

   Calculating dependencies... done!
   [ebuild  rR   ~] dev-libs/libjcat-0.1.1 

   Would you like to merge these packages? [Yes/No] no

   Quitting.

Package "dev-libs/libjcat"  does in fact  have a "man" USE flag,  and it
provides a single manual page, "/usr/share/man/man1/jcat-tool.1.bz2".  I
don't know for sure though  whether my adding  'LANG="en_GB"'  to "/etc/
portage/make.conf"  and doing  all the  magic in the  Gentoo Locaization
Guide  caused Portage's desire  to re-emerge  that package  or something
totally different.

But there are  other packages installed  with the "man" USE flag,  which
didn't even flinch.   In particular  there is package  "sys-apps/shadow"
which among other things provides the "passwd" command and which doesn't
honour the "man" USE flag at all, but is quite polyglot:

   # cd /usr/share/man
   # find . -type f -name 'passwd*'
   ./ru/man1/passwd.1.bz2
   ./man1/passwd.1.bz2
   ./sv/man1/passwd.1.bz2
   ./man3/passwd2des.3
   ./ja/man1/passwd.1.bz2
   ./it/man1/passwd.1.bz2
   ./fr/man1/passwd.1.bz2
   ./hu/man1/passwd.1.bz2
   ./de/man1/passwd.1.bz2
   ./tr/man1/passwd.1.bz2
   ./zh_CN/man1/passwd.1.bz2
   ./man5/passwd.5.bz2
   #

So the question  how to get rid  of all these  unnecessary  languages is
still open.

Sincerely,
  Rainer
