[Mono-aspnet-list] mod-mono-server4.exe crashes System.MissingMethodException: Method not found: 'System.Configuration.IConfigurationSectionHandler.Create'.

CentOS 5.6 - XSP 2.10.2

If MonoServerPath  points to mod-mono-server2.exe everything is fine.

If MonoServerPath  points to mod-mono-server4.exe, the application
throws an exception trying to get application settings:

System.MissingMethodException: Method not found:
'System.Configuration.IConfigurationSectionHandler.Create'.
