Hi,

Attempting to 'guix refresh gambit-c' currently fails like:

--8<---cut here---start->8---
./pre-inst-env guix refresh gambit-c
Backtrace:

ice-9/boot-9.scm:1685:16: In procedure raise-exception:
no candidates found in rewrite-url
--8<---cut here---end--->8---

That's because http-fetch/cached doesn't following redirection:

--8<---cut here---start->8---
$ curl http://www.gambitscheme.org/4.9.4

301 Moved Permanently

301 Moved Permanently
nginx


--8<---cut here---end--->8---

which means the page is reachable but doesn't contain the expected
content.
