make install doesn't install MySQLdb

Using a MySQL database, the install process is interrupted like this :

ImportError: No module named MySQLdb

I can work around this problem by creating a symbolic link of Debian's MySQLdb into lib/python2.7/site-packages.

I understand this is somewhat documented, but doesn't take into account the case where the database may already be configured for MySQL prior to running make install.
