Hi,

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

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

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
<html>
<head><title>301 Moved Permanently</title></head>
<body>
<center><h1>301 Moved Permanently</h1></center>
<hr><center>nginx</center>
</body>
</html>
--8<---------------cut here---------------end--------------->8---

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

Thanks,
Maxim
