Thanks everyone for the hints.

Indeed I was overly confused : I had previously manually set them to
empty values to workaround the proxy setting made by pybuild internally,
so that the build would effectively access the network... and then I
forgot why I had done that... and of course I hadn't documented that ;)
Sorry about the bothering.
But, then there's still the option of maybe mocking the tests so that we
can proxy locally a copy of the document being fetched... but I'll let
that for another day ;)
