Hi,

My port compiles fine on FreeBSD 12 and 13 but fails on 14.

I tried older llvm versions but that does not help. So I get the idea it has something to do with the c++ libraries in 14.0.
Is this a known issue?
Any advice or suggestion on how to resolve this? Or should this go to upstream mongodb?
