+The test fails when ${D} is exported in the environment. It actually _shouldn't_
+be exported in src_test anyway, but Portage isn't yet fixed for this because
+it'll break misbehaving ebuilds (see e.g. pkgcheck's VariableScope warnings).
+
+Upstream are currently discussing other patches and work to find other cases
+of environment contamination.
