SWH: fallback error

[zimoun]

Hi,

In order to check if the SWH fallback works, time to time, I test it.  I
have a variant package of hello defined here:

   <https://github.com/zimoun/channel-example>

The source had been archived on SWH long time ago (via their Web
submission or via “guix lint -c archival”).  

Using Guix 16ef7b4, I get this:

--8<---------------cut here---------------start------------->8---
$ guix build -L /tmp/channel-example/ hi -S

The revision is found but then an error.  Hum?

Any clue?
