+      <b>Hint:</b> polymake currently undergoes a major refactoring of its codebase.
+      One reason is an incompatibility of the current code with perl version 5.38 and its successors.
+      This is why polymake temporarily vanished from several Linux distributions.
+      Users should download our tarballs with a <a href="/doku.php/install/jll">prebuilt polymake</a> (including a suitable perl).
