FreeBSD, Python and SSL certificate validation

When not explicitely giving a SSL certificate file to Python request, it will expect the system certificates to be in /etc/ssl/cert.pem.

However, in FreeBSD, they are in /usr/local/etc/ssl/cert.pem, resulting in the following error:

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600)>

The quick and dirty fix for this was the following:

ln -s /usr/local/etc/ssl/cert.pem /etc/ssl/cert.pem

Now Python can find the system certificates, and we don’t need to explicitely give the certificate file to request when doing the request (espacially useful when request is used by another module that don’t allow to customize the certificates).
