That form of message means that the matching module is not present in the running nginx.

"dynamic" means that at configure time, that module was set to be built
as a thing that can be loaded at run-time.

But until it actually is loaded, it is not present in the running nginx.

See http://nginx.org/r/load_module

Maybe the older version included a "load_module" directive that the newer version does not?

Good luck with it,
