Curl with ARES support
It would be nice to have Curl compiled with cares by default. With this in place, it would be possible to use pfSense/OpenVPN/Yubikey-authentication out of the box without the need to create a separate curl-package and port it into the pfsense box.
It seems as if curl is compiled with threads, and linked with libpthread but su isn't. So when doing dlopen() on the pam module libpthread is loaded to late.
