File not found. Seems to be missing file and that's why not installable on new system.

The archive does not exist on the servers because I have not set up a build machine for macOS 15 for arm64 yet. That's not really a bug; it's just a missing feature. See #60756.

When MacPorts can't find an archive on the servers, it builds from source on your system. That appears to be failing. That's a bug. Please attach the main.log file so that we can investigate what has gone wrong.

[vitaligedz]

Right, thanks. Just provided info about new system and would be nice to see its working soon.

Attached main.log

Ok, the log says:

:info:build vmem_sbrk.c:137:14: error: incompatible pointer to integer conversion assigning to 'int' from 'void *' [-Wint-conversion]
:info:build   137 |   brk_result = brk((void *)new_brk);
:info:build       |              ^ ~~~~~~~~~~~~~~~~~~~~
:info:build 2 warnings and 1 error generated.

Incompatible pointer to integer conversions are a new error in the version of clang in Xcode 16.

Unfortunately, ​the developers of umem no longer exist so they won't help us with this. (Nevertheless the problem should be reported in their issue tracker.)
