You don't use any of these imports except for base_packages

+from autotest_lib.client.common_lib import utils, base_packages
+
+
+class SiteHttpFetcher(base_packages.HttpFetcher):
+    # shortcut quick http test for now since our dev server does not support
+    # this operation.
+    def _quick_http_test(self):
+        return
+
+
+class SitePackageManager(base_packages.BasePackageManager):
+    def get_fetcher(self, url):
+        if url.startswith('http://'):
+            return SiteHttpFetcher(self, url)
+        else:
+            return base_packages.BasePackageManager.get_fetcher(self, url)
