Subject: bug#26346: [PATCH 19/20] build-system/asdf: Handle versioned asdf dependencies.
Date: Sat,  8 Apr 2017 23:43:32 -0400

Add support for depencies of the form (:version <name> <version>).

* guix/build/lisp-utils.scm (normalize-dependency): New variable.
(make-asd-file)[dependencies]: Use it to generate dependencies with normalized
names.
[dependency-name]: New variable.
[registry]: Use it to flatten the normalized dependencies.
