Just an update. Compiling nginx 1.0.11 manually worked for me. So to have my manually compiled version match the same file locations as what I get from pacman, I used what I found in the
PKGBUILD.
$this->bbcode_second_pass_code('', '_doc_root=/usr/share/nginx/http
_server_root=/etc/nginx
_conf_path=${_server_root}/conf
_tmp_path=/var/spool/nginx
_log_path=/var/log/nginx
_user=http
_group=http
./configure \
--prefix=${_server_root} \
--sbin-path=/usr/sbin/nginx \
--pid-path=/var/run/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--http-client-body-temp-path=${_tmp_path}/client_body_temp \
--http-proxy-temp-path=${_tmp_path}/proxy_temp \
--http-fastcgi-temp-path=${_tmp_path}/fastcgi_temp \
--http-log-path=${_log_path}/access.log \
--error-log-path=${_log_path}/error.log \

--add-module=/usr/lib/passenger/ext/nginx \

About the only change from the PKGBUILD is that I removed the line, "--add-module=/usr/lib/passenger/ext/nginx"
