ユムは何らかの理由で破産した

MySQLクライアントをインストールしようとすると、この迷惑なメッセージが表示されます。まだ正解が見つかりません。

[root@localhost Downloads]# yum install mysql-bench
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   /usr/lib64/python2.7/site-packages/pycurl.so: undefined symbol: CRYPTO_num_locks

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.7.5 (default, Jun 17 2014, 18:11:42) 
[GCC 4.8.2 20140120 (Red Hat 4.8.2-16)]

If you cannot solve this problem yourself, please go to
