The relevant part is:

:info:build ../../../../libs-external/USI++/version:1:1: error: expected unqualified-id
:info:build 1.92
:info:build ^

This happens because you are using a compiler that supports C++20 and its <version> header, and the project has a VERSION file in its root directory, and the project uses an -I flag pointing to the root directory, and you are on a case-insensitive filesystem.

Solutions are for the project not to use an -I flag pointing to the root directory (and relocate any files that need to be included from there to other directories), or for the project to rename the VERSION file (and update any references to that file elsewhere in the code).

For more background, see ​https://bugs.llvm.org/show_bug.cgi?id=42540

This is an upstream problem that needs to be ​reported to the developers. However, since the last release of this software was in 2005, the developer may no longer exist or care, so we may need to develop the fix ourselves.

There are many similar reports about other ports in the MacPorts issue tracker (and in other projects' issue trackers) if you want to see more examples of how this was handled.

[ryandesign (Ryan Carsten Schmidt)]

And in this case, "the project" refers not xprobe2 but the USI++ external library that it bundles. Still appropriate to report both to the developers of xprobe2 (since they need to update to a fixed version of USI++ if it exists) and to the developers of USI++ (in case a fixed version does not yet exist).

[ryandesign (Ryan Carsten Schmidt)]

Is there any value to this software anymore? It has been abandoned by its developers and we have an unresolved 15-year-old ticket saying it does not work. When I tried to build it, I encountered additional errors. I suggest deleting the port.
