Thanks, Ricardo.  For now, I've changed my local 'guix' script to this:

  #!/bin/sh
  source /var/guix/gcroots/per-user/mhw/environment-guix/etc/profile
  exec /home/mhw/guix/pre-inst-env guix "$@"

Where /var/guix/gcroots/per-user/mhw/environment-guix is a symlink
pointing to the profile created by 'guix environment guix'.  I update
this environment periodically, as needed.

If there's a good reason to avoid implementing Ricardo's suggestion, I
don't mind keeping my modified 'guix' script above, but I confess that I
don't yet understand the cause of your reluctance.

Anyway, it seems that my practice of running 'guix' from a private git
checkout is becoming increasingly awkward to arrange.  I would be
pleased if this mode of operation were better supported.

     Regards,
       Mark
