Subject: [PATCH 2/2] build: pull: Fix compilation list construction.

From: Mathieu Othacehe <[email-masked]>
Date: Fri, 19 May 2017 09:56:23 +0200

* guix/build/pull.scm (depends-on-guile-ssh?): Remove.
(all-scheme-files): Use "scheme-modules" to detect all loadable
modules in given directory and rebuild a file list from those modules.
