Brief summary of issue:

I've tried on two machines building nginx with the --with-headers-more-module option, to get the headers more module which I try to include via
load_module modules/ngx_http_headers_more_filter_module.so;
in nginx.conf.
Yet, nginx complains that the file does not exist and I don't see any "modules" directory in the nginx installation path.
A find for the file (or any .so) does not return anything.

The complete command that you issued:

brew install --verbose nginx-full --with-headers-more-module

We still use static linking modules. load_module may not even be used, dynamic loading issue #168.
