Gcc in Debian 11 can build Rspamd and libstdc++ from Debian 11 is 
compatible with the modern C++. This is not the case for Debian 10, and 
that's the main issue. Libunwind-16 comes from llvm libc++. 
Unfortunately, in this case Rspamd cannot be linked with hyperscan, as 
hyperscan uses libstdc++. So there is just no good solution for Debian 
10 (aside of building hyperscan from the sources and linking it with 
libc++ from llvm). You can try to compile Rspamd on your own, no doubts, 
but I think you'll struggle with the same issues.
