libcurl link-time ssl backend (nss) is different from compile-time ssl backend (openssl)

CeotOS系统 Python 安装pycurl时报错：

import pycurl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (openssl)

解决的方法：

pip uninstall pycurl
export PYCURL_SSL_LIBRARY=nss
easy_install pycurl

需要注意的是之前用pip安装的，然后卸载掉以后，一定要用easy_install安装才可以导入成功
