If you have already install Macports

$ sudo port install py26-mysql

Else, Install Macports

url: https://distfiles.macports.org/MacPorts/

download: MacPorts-2.1.2.tar.gz

On terminal

$ tar zxvf MacPorts-2.1.2.tar.gz

$ cd MacPorts-2.1.2

$ ./configure

$ make

$ sudo make install

/opt/local/bin should be added to my $PATH

$ vim ~/.bashrc

export PATH=$PATH:/opt/local/bin

$ source ~/.bashrc

$ sudo port -v selfupdate

$ sudo port search python | grep mysql

$ sudo port install py26-mysql

Using Macports didnot solve my problem.

So I will use the MySQL-python binaries.

URL: http://sourceforge.net/projects/mysql-python/

Download: MySQL-python-1.2.4b4.tar.gz

Terminal:

$ tar zxvf MySQL-python-1.2.4b4.tar.gz

$ cd MySQL-python-1.2.4b4

$ vim site.cfg

## Comment this line

#mysql_config = /usr/local/bin/mysql_config

## provide path to mysql_config

mysql_config = /usr/local/mysql/bin/mysql_config

$ python setup.py build

$ sudo python setup.py install

Looks good so far. Check if everything works

$ python

Rerun the Google App Engine.

I was not able to solve the problem. The ERROR message still stays the same.
