0.8 fails to build when ld cannot find -lsasl2

[lfam]

I'm trying to build ncmpcpp 0.8 in GNU Guix [0].

Unless I make Cyrus SASL available in the build environment, it fails as shown below. Is this dependency expected? Or is it a bug in ncmpcpp's build system, or perhaps in the Guix package tree?

I suspect an issue in our packaging of openldap, which is a dependency of curl.
