Why has my emacs flyspell aspell stopped working?

[George Clemmer]

Hello,

emacs 'm-x flyspell-buffer', which worked great for years, is now doing  ...

Debugger entered--Lisp error: (error "Error: No word lists can be found for the 
language \"en_US\".")
  signal(error ("Error: No word lists can be found for the language 
\"en_US\"."))
  error("%s" "Error: No word lists can be found for the language \"en_US\".")

I believe it started with a system/user profile update in mid-December.
Naturally I ignored it hoping it would heal up with the next update ;-)

Anyway, I manage the system using Guix from Git. Today I pulled git
describe v0.16.0-629-g6df4d8338 and rebuilt guix. Then I did 'sudo -E
guix system --skip-checks --fallback --cores=7 --max-jobs=10 reconfigure
sys.scm', rebooted, and 'guix package -m .manifest.scm' (where 'guix'
calls a script that runs './pre-ins-env guix'). Sadly, still no joy :-(

FWIW, I get the same error when I use
'/home/glc/.config/guix/current/bin/guix package -m .manifest.scm',
which is guix (GNU Guix) bd208a13ef4c203cf9035c0ccf454a60c1949c58.

Any idea what has changed and/or I am doing wrong?

TIA - George
