最近在linux上部署aeroo报表引擎的时候，遇到了问题，先上配置：
------------------------------------------------------------------------
系统：centos 6.5 64bit
Python:2.7.5(configure时加入参数--enable-shared,--enable-unicode=ucs4)
OpenOffice:4.0(linux64bit)
openoffice python:2.7.5
------------------------------------------------------------------------
OpenOffice安装好后，并让其以8100后台运行，执行netstat -tnl可以看到其正在后台运行
安装了aeroo所需要的aeroolib和genshi(0.6)
安装report_aeroo_ooo模块时报错如下：
dynamic module not initialized properly

查看系统python的sys.maxunicode为1114111
查看openoffice的sys.maxunicode为65535

请问各位为什么条件满足的情况下aeroo的ooo环境安装不成功？是系统python和openoffice的python的位数不兼容吗？如果是的话有什么解决方案那？
