ngx_http_upstream_keepalive error ?

[George]

Hi first time trying to compile Nginx with ngx_http_upstream_keepalive
module support and seems I am getting an error at make stage while
compiling with Nginx v1.1.19 ?

configure line:

./configure --sbin-path=/usr/local/sbin
--conf-path=/usr/local/nginx/conf/nginx.conf --with-http_ssl_module
--with-http_gzip_static_module --with-http_stub_status_module
--with-http_sub_module --with-http_addition_module
--with-http_secure_link_module --with-http_flv_module
--with-http_realip_module --add-module=../ngx-fancyindex-ngx-fancyindex
--add-module=../ngx_cache_purge-1.4
--add-module=../nginx-accesskey-2.0.3
--add-module=../agentzh-memc-nginx-module-4007350
--add-module=../agentzh-srcache-nginx-module-fa2da58
--add-module=../ngx_http_upstream_keepalive-d9ac9ad67f45
--with-openssl=../openssl-1.0.0e --with-openssl-opt="enable-tlsext"

the error at make stage
