sudo pip install mecab-python

# (See this as well: http://d.hatena.ne.jp/addition/20130405/1365089276)
# Basically, you should edit the file /etc/ld.so.conf
# and its content should look like this
include ld.so.conf.d/*.conf
/usr/local/lib
# and then run this command:
sudo ldconfig

# Alternatively, you can add mecab's lib folder to LD_LIBRARY_PATH to tell Python where to find the SO file.
# E.g. Add this to your .bashrc file
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/home/username/local/mecab/lib

# There are two important executable files for mecab which are mecab-config and mecab.
# These two files can be found in mecab installation folder (by default they are at /usr/bin/mecab and /usr/bin/mecab-config)
