Hee, I saw this exact same issue. I fixed it by making a softlink
/usr/lib/llvm-18/lib/libclang-cpp.so -> libclang-cpp.so.18.1. It's not
clear to me why install didn't create the link like it does with other
libraries.

Please let me know if this works (will at least update the doc) and
whatever other issue you're having!
