+# Since python ebuilds remove the 'email' module when USE=build
+# is enabled, use a local import so that
+# portage.proxy.lazyimport._preload_portage_submodules()
+# can load this module even though the 'email' module is missing.
+# The elog mail modules won't work, but at least an ImportError
+# won't cause portage to crash during stage builds. Since the
+# 'smtlib' module imports the 'email' module, that's imported
+# locally as well.
