 Without `gnutls` installed:
 {{{

 :info:configure configure: WARNING:

 {{{

 With `gnutls` installed:
 {{{
 :info:configure checking for ntbtls-config... no
 :info:configure checking for NTBTLS - version >= 0.1.0... no
 :info:configure checking for LIBGNUTLS... yes
 }}}
 {{{

 {{{
 :info:configure         TLS support:         gnutls
 }}}

 I don’t know how you want to deal with this. I think it would be best to
 add the dependency on `gnutls` so that TLS is always available, but that
 means requiring `curl +gnutls`. At a minimum, the port should configure
 with `--disable-gnutls` to prevent the opportunistic behavior.
