title: Getting Unknown flag: -v when i run protoc -version in my ubuntu
body: <p>I'm getting the following message when i run protoc -version in my ubuntu terminal.</p>
  
  <p>Unknown flag: -v</p>
  
  <p>Earlier to this, I had got the following error when I ran protoc -version. I found a solution through google and ran "sudo ldconfig /usr/local/lib". After running that, I'm getting the Unknown flag message as mentioned above. Can anyone help me to resolve this? Thanks in advance.</p>
