I will defer to the Guix maintainers on this question, but I just wanted
to point out that since 'offlineimap' is the _only_ package in Guix that
depends on the 'python2-rfc6555' package, it's quite painless to work
around this particular issue using Guix's "--without-tests" package
transformation option.

From the command line, you can simply do this:

  guix build offlineimap --without-tests=python2-rfc6555

Within an OS configuration, or within a profile "manifest" file (if you
use "guix package --manifest", which is highly recommended), you can use
the following Scheme expression in place of 'offlineimap':

--8<---------------cut here---------------start------------->8---
  (let ((transform (options->transformation
                    '((without-tests . "python2-rfc6555")))))
    (transform offlineimap))
--8<---------------cut here---------------end--------------->8---

Note that you'll also need to put "(use-modules (guix transformations))"
at the top of the file, to import the 'options->transformation'
procedure.

Please let us know if this works for you.

     Thanks,
       Mark
