I'm starting a new Python environment on a new Ubuntu installation. You
never know when a huge yak will show up and demand to be shaved.
I tried following the directions in the README, and found that a couple
of steps were missing. I've added those.
When you follow those steps, it appears to install the MeCab Korean
dictionary in `/usr/lib/x86_64-linux-gnu/mecab/dic`, which was none
of the paths we were checking, so I've added that as a search path.
