cgal4: openscad and other ports depending on cgal4 fail to build

[tmladek (Tomáš Mládek)]

I'm using the latest MacPorts version, I tried port cleaning the port and trying to reinstall, but it still fails to build. In the log I was pointed to (/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_science_openscad/openscad/main.log), I found at least the following errors (repeated a few times):

It looks like this issue could be related: ​https://github.com/CGAL/cgal/issues/8313 and so it could be an issue with cgal, but the health of the cgal4 port seems to be fine on Tahoe/arm64, whereas the openscad port seems to fail currently: ​https://build.macports.org/builders/ports-26_arm64-builder/builds/15492

I'm completely new to MacPorts and I don't have too much visibility into openscad's build process so some of this might be off, but this is as far as I got. Thanks in advance!

I think you're exactly right. The fix for that issue needs to be added to our cgal4 port. (Upstream only fixed it for cgal 5.5 and later.)
