No, that's the wrong library -- we link against openssl's libcrypto.
Is libssl-dev installed?

NB: I've yet to be able to build pacman successfully against anything
involving gnutls, and i've even had build failures when libarchive
linked to gnutls (though that may have been resolved by binutils 2.22).

This is ghostscript... I assure you we don't link against this. It
should all be covered by openssl.
