[alibaba/tengine]无法安装ngx_http_dyups_module

对tengin 2.3.1 进行编译安装时，

export LUAJIT_LIB=/user/local/lib
    export LUAJIT_INC=/usr/local/include/luajit-2.1

    ./configure --add-module=./ngx_cache_purge-2.3 \
    --with-http_stub_status_module \
    --with-http_ssl_module --with-http_realip_module  \
    --with-http_gzip_static_module \
    --with-ld-opt="-Wl,-rpath,/user/local/lib" \
    --add-module=./lua-nginx-module-0.10.15 \
    --add-dynamic-module=./ngx_http_dyups_module-0.2.9 \
    --with-jemalloc=./jemalloc-5.2.1

在编译阶段报错：

这个如何解决呢？
