-    This version of Package::Stash conflicts with the version of
-    $mod ($installed) you have installed.
-
-    You will need to upgrade $mod after installing
-    this version of Package::Stash.
+    Your toolchain doesn't support configure_requires, so Dist::CheckConflicts
+    hasn't been installed yet. You should check for conflicting modules
+    manually using the 'package-stash-conflicts' script that is installed with
+    this distribution once the installation finishes.
