解决：

查看Python路径相关环境变量的意义。

• PYTHONHOME ：指定 Python 的标准库。
• PYTHONPATH ：用于扩充 Python 查找模块文件的路径。

这里是导入 site 模块时出错，所以应该在 PYTHONPATH 上增加 site 模块的路径。

查找site相关文件的路径：

[root@tZ etc]# find / -name site.py*
/usr/lib64/python2.7/site.pyc
/usr/lib64/python2.7/site.py
/usr/lib64/python2.7/site.pyo

增加路径到环境变量：

[root@host-10-10-18-131 Python-2.7.5]# export PYTHONPATH=$PYTHONPATH:/usr/local/python2.7.5
[root@host-10-10-18-131 Python-2.7.5]# make -j 4
./python -E -S -m sysconfig --generate-posix-vars
