Yes and no. :-)

It depends the Guix revision.  Using a revision from January as 29efa27,
it works.  But using 86d580c from April, it fails with:

In procedure connect: Network is unreachable

which passes with 29efa27.  And indeed, using 86d580c, “guix import pypi
num2words -r” passes without any error, downloading from the exact same
URL. Hum?!

Well, I do not know which change impacts this regression.


Cheers,
