modernmt: Getting an error while creating a new engine "EN-AR"

Hello support team,

I followed the instructions mentioned here https://github.com/ModernMT/MMT/issues/208#issuecomment-266766252, but I am getting the following error when I type the following command:

./mmt create en ar examples/data/train

I am also getting the same error when using the command in readme

./mmt create en ar examples/data/train

Here is the full error log:

`root@modernmt-VirtualBox:/home/modernmt/Downloads/mmt# ./mmt create en ar examples/data/train

P.S. I am using Ubuntu 14.04 VirtualBox image to run this test.
