nanoc: bundle / cri/option_parser / foreman interaction error

bundle exec foreman start used to correctly run nanoc view without complaint; now nanoc errors with a cri/option_parser error. Running the two individual commands in foreman’s Procfile works fine:

Procfile:

watch: bundle exec guard
nanoc_view: bundle exec nanoc view

% bundle exec guard

14:03:59 - INFO - Compilation succeeded.
14:03:59 - INFO - LiveReload is waiting for a browser to connect.
14:03:59 - INFO - Guard is now watching at 'jm3.net'
[1] guard(main)>

% bundle exec nanoc view

but

% bundle exec foreman start

which runs the same two commands, now bombs with a cri/option_parse error:
