Hi Guix,

When trying to run guix package --show with packages from the
(gnu packages ssh) module, such as openssh, guile-ssh, and libssh, I get 
the following stack trace:

$ guix package --show=openssh

To me, the error looks like a missing module import or simmilar, but I 
can't spot it. Perhaps it is something else.

Best,
Jack

Hi Jack,

Fixed in 71b4974a40347bdc651c3a1f923780733d96ded7.

The lesson is: when inheriting from a package, do it in the module where
it’s defined.

Thanks,
Ludo’.
