+Versioneer does not work in the Guix build container because:
+
+* VCS information is unavailable
+* the build directory does not have the supported "$name-$version" format
+* as of 0.21, versioneer has no way to override the discovered values
+
+This patch adds support for extracting version from the
+'/tmp/guix-build-foo-0.1.drv-0' style directories created by the daemon.
