I'm successfully using this package with this change.

I don't know if this is the "right way" to solve this. Your thoughts?

To clarify, here is what happens on Debian Jessie without this change:

$ acme-client -nN example.com
acme-client: tls_config_set_ca_file: failed to open CA file '/etc/ssl/cert.pem': No such file or directory: No such file or directory

And here are the upstream notes on this subject [0]:

"You can also set DEFAULT_CA_FILE for the location of the certificate
file loaded by libtls."

The upstream maintainer recommends setting this value in 'config.h', but
it's only used in 'http.c', so I thought this solution would be a little
easier to read.

LGTM. I did not know libressl maintains their own root trust.
