Unfortunately I don't have access to a macOS 15.1 machine to test the build of SBCL nor do I anticipate this changing in the near future as there are very real concerns about upgrading my aging equipment.

Therefore I can do very little to resolve your problems other than shepherd plausible patches from others.

Upon closer inspection of attachment:main.log​ it seems that @murrayE is attempting to build sbcl-1.5.3. Please use sbcl-1.5.7 or later, as the previous versions of SBCL will not run on macOS 10.15 Catalina.

Since SBCL has now released support macOS Catalina I have updated the port to use sbcl-1.5.8 <​https://github.com/macports/macports-ports/commit/217bba0a4780db4ed3fb505b2cf53845d03c8aa6> as well.
