Problem with nginx

[Jim Trigg]

When I try to build nginx using poudriere, I get an error in mod_zip 
even though I've made sure that HTTP_ZIP is unset. How can I correct this?

/wrkdirs/usr/ports/www/nginx/work/mod_zip-74ef235/ngx_http_zip_module.c:74:4: 
error: no member named 'charset' in ''
           offsetof(ngx_http_zip_conf_t, charset),
