Hello,

Weechat uses libcurl, which uses GnuTLS and does not honor
‘SSL_CERT_DIR’, ‘SSL_CERT_FILE’, and ‘CURL_CA_BUNDLE’.

Instead, GnuTLS defaults to looking for certificates in /etc/ssl/certs,
and it is up to the application to search for certificates in additional
places.

This has been discussed at
<https://lists.gnu.org/archive/html/guix-devel/2017-01/msg00516.html>
but there’s no good solution yet.

Thanks,
Ludo’.
