Re: Why lang/gcc14-devel builds are failing on the build servers: needs USES= compiler:c++14-lang (or higher) instead of compiler:c++11-lang

Ok, let's try other way:

Suppose that port compiles with c++17. Do you need to set
"compiler:c++17-lang' capability?
No, base clang supports it. Same for the other capabilities listed in
porter's handbook.
