--with-system-expat: This switch enables linking against system version of Expat.
--with-system-ffi: This switch enables linking against system version of libffi. Remove if you have not installed libffi-3.2.1.
--enable-unicode=ucs4: This switch enables 32bit Unicode support in Python.
要求python编译的时候,需要有动态链接库即加上--enable-shared

将tab.py放到/usr/lib/python2.7/site-packages/
