This option is only used when installing Django 6.x with a MySQL database.

If enabled, Virtualmin will install the required system build packages and compile the `mysqlclient` Python database driver automatically during the Django installation.

If disabled, Virtualmin will not install those build packages or compile the driver. Choose this only if `mysqlclient` is already installed for the selected Python version, or if you plan to install it yourself before retrying this Django install.

This setting has no effect for PostgreSQL installs, and Django versions before 6 continue to use the older package-based MySQL driver path.
