+      <b>Hint:</b> polymake currently undergoes a major refactoring of its codebase.
+      One reason are changes in perl version 5.38 and its successors that restrict access to various internal functions.
+      This is why polymake temporarily vanished from several Linux distributions.
+      Users can download our tarballs with a <a href="/doku.php/install/jll"><img heigth="20" width="20" alt="Download" src="/theme_files/images/download-pm.png"/>prebuilt polymake</a> (including a suitable perl).<br/>
+      <b>Update:</b> The latest polymake 4.11 restores compatibility with perl 5.38 but it is unclear if these workarounds will stay possible for future perl releases.
