I've just installed guix on a fresh Ubuntu 15.10 - guix (GNU Guix) 0.9.0. The first run of 'guix pull' fails. The log[1] includes the error: Starting download of /gnu/store/n7hw4dgm9qh1ihhb13jf5a1ll0wgf6ns-pkg-config-0.28.tar.gz From http://pkgconfig.freedesktop.org/releases/pkg-config-0.28.tar.gz... following redirection to ` https://pkg-config.freedesktop.org/releases/pkg-config-0.28.tar.gz'... ;;; Failed to autoload make-session in (gnutls): ;;; ERROR: missing interface for module (gnutls) ERROR: In procedure module-lookup: Unbound variable: make-session Am I doing something wrong?
