mysql-python install problem using virtualenv, windows, pip

Today I was working with Django and MySQL using "ENVIRONMENTVARIABLE". But when I was trying to sync my MySQL db. It was generating a error. something like this.

(test_south) C:\Users\a\Envs\test_south\test_project>python manage.py syncdb
Traceback (most recent call last):

    raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e)
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named _mysql






Then I was trying to install MySQLdb using pip command. My pip command was: pip install MySQL-python. But at time I faced a another problem. Like


building '_mysql' extension
C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\amd64\cl.exe /c /nologo /Ox /MD /W3 /GS- /DNDEBUG -Dversion_info=(1,2,4,'final',1) -D__versi
on__=1.2.4 "-IC:\Program Files\MySQL\Connector C++ 1.1.3\include" -IC:\Python27\include -IC:\Users\a\Envs\test_south\PC /Tc_mysql.c /Fobuild\temp.win-

_mysql.c
_mysql.c(42) : fatal error C1083: Cannot open include file: 'config-win.h': No such file or directory
error: command '"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\amd64\cl.exe"' failed with exit status 2


How could I solved this problem?

1] First I went to the http://www.codegood.com/download/11/ this location to download the binary of mysql-python64bit. Which is MySQL-python-1.2.3.win-amd64-py2.7.exe
2] Then I installed the binary in my C:\Python27 folder location
3] Then I went to the Lib\site-package folder and copy all the files and folder which are related to the mysql
4] Then I just paste the files in my environmentvariable location. which is

then pressed the syncdb command. And it was working :-)
