How to install for "dstat_mysql5_io failed"

I tried to check iowait by dstat but it show like...

# dstat --mysql5-io
Module dstat_mysql5_io failed to load. (No module named MySQLdb)
None of the stats you selected are available.

Install this for CentOS 6.x

# yum install MySQL-python

if you use other OS, try these

# aptitude search mysqldb
# yum search mysqldb
# emerge --search mysqldb
# pacman -Ss mysqldb

And setup MySQL user & password

DSTAT_MYSQL_USER
DSTAT_MYSQL_PWD
