My OS is Ubuntu 14.04 and after installing the mitmproxy as [Installation](http://docs.mitmproxy.org/en/stable/install.html) and run it, error occur:

```
Traceback (most recent call last):

OPENSSLDIR: "/usr/local/ssl"
root@vultr:~# mitmproxy --version
mitmproxy 1.0.2

```

I manually updated the openssl after installing mitmproxy, but the system info of mitmproxy remains old version of openssl:

```
root@vultr:~# mitmproxy --sysinfo
Mitmproxy version: 1.0.2
Python version: 3.5.2
Platform: Linux-3.13.0-105-generic-x86_64-with-debian-jessie-sid
SSL version: OpenSSL 1.0.1f 6 Jan 2014
Linux distro: debian jessie/sid 

```

Maybe I should reinstall the mitmproxy??

What’s this problem and how to fix it??
