Dear All,
I am trying to install JuPyMake but it fails with a linker issue:

```
I have polymake 4.11 installed through my system package manager (gentoo) and
I am using gcc 13.2.1. The same issue happens if I try to install JuPiMake
though the sage build system, using pip through PyPi in a virtualenv, and
from sources.
Any idea on what the issue could be?
Thanks
Salvatore
