Sqlite db error build iphone4

Hello everyone,

I'm trying to connect to a db.sqlite with basic unity and a IOS license to develop an app for the iphone 4.

I created my db (name.sqlite) and I put this file out of the Assets folder. Then I took the two dll (Mono.Data.SqliteClient.dll and System.Data.dll) and I put this file out of the Assets folder.

In my code (JavaScript) I do the following imports:

 import System.Data;
 import Mono.Data.SqliteClient;

When I try to build this code for iOS platform:

 import System.Data;
 import Mono.Data.SqliteClient;
 
 private var connectionString: String;
 private var dbcon : SqliteConnection; //the instantiation of this creates errors
 ...
 ...

this generated the following error:

• ArgumentException: The Assembly Mono.Data.SqliteClient is referenced by Assembly-UnityScript. But the dll is not allowed to be included or could not be found. Error building Player: Extracting referenced dlls failed. Exception: Error building Player: Extracting referenced dlls failed.

Why???????
