I made a mistake opening this as a new ticket. Actually, I got this error when trying once again to install upx. I removed and reinstalled the commandlinetools (which led to successfully being able to install hugo and tippecanoe, both of which had failed earlier). Then I tried to install upx. This time it ran further than before but failed with the above error (python310 related). This really should be a part of #70834(​https://trac.macports.org/ticket/70834)
