无法安装sqwebmail, 哪位高手能帮助我？

我已装好的 sqwebmail+mysql+vpopmail...,能用 foxmail收发邮件但安装sqwebmail, 一直不行，我甚至在不同服务器上重装几次整个系统,还是不行. 我用的是redflag 2.0，
现象如下, 请高手指点.
开始我运行以下代码:
  INCS=-I/usr/include/mysql
   export INCS
   LIBS="-L/usr/lib/mysql -lmysqlclient -lz"
   export LIBS
   CPPFLAGS=-I/usr/include/mysql
   LDFLAGS=-L/usr/lib/mysql
   export CPPFLAGS
   export LDFLAGS
  ./configure --with-cachedir --without-gzip --enable-webpass=yes
  --enable-softtimeout=300 --enable-autopurge=180 --enable-maxpurge=180
  --with-htmllibdir=/home/httpd/html/sqwebmail
  --enable-cgibindir=/home/httpd/cgi-bin
  --enable-imagedir=/home/httpd/images/sqwebmail
  --enableimageurl=/images/sqwebmail/
  --enable-mimecharset=gb2312 --with-maxargsize=5000000
  --with-maxformargsize=5000000 --with-maxmsgsize=5000000 --without-ispell
  --with-authshadow --without-authmysql --with-authldap --with-authuserdb
  --with-authpwd --without-authpam --with-authvchkpw --without-authdaemon
我查了config.log,最后三句是：
checking where to install sqwebmai cgi binary
checking where to install images
checking for gpg
