This is due to a change in r-curl. We patched it to respect the
CURL_CA_BUNDLE environment variable, not just when it’s used on Windows.
The code has changed since we developed the patch. Now the
CURLOPT_CAINFO option is only set (in
curl/src/handle.c:set_handle_defaults) when _WIN32 is defined and when
tlsinfo->backend == CURLSSLBACKEND_OPENSSL. Neither of these cases
apply for Guix.
I’ve adjusted the patch in r-curl.
Thank you for the report!
