[Mono-osx] Problem with loading OSX libc ( malloc)

Downloaded some SQLite sources from the good people at Finisar, and  
compiled.  I get however an exception like this on run.

  The exception is   at (wrapper managed-to-native)  
Finisar.SQLite.Util:malloc (uint)
   at Finisar.SQLite.Util.AllocateUnmanagedMemory (Int32 size) [0x00000]
   at Finisar.SQLite.MarshalStr.GetSQLiteStr () [0x00000]
   at Finisar.SQLite.sqlite3.open (System.String filename) [0x00000]
   at Finisar.SQLite.SQLiteConnection.Open () [0x00000]

Finisar imports the libc as so

private extern static IntPtr malloc(UInt32 bytes);

and calls it like so

	public static IntPtr AllocateUnmanagedMemory( Int32 size )
			if( (int)Environment.OSVersion.Platform == UNIX )
				return malloc((UInt32)1000);
				return HeapAlloc( GetProcessHeap(), 0, (UInt32)size );

  Anybody got any ideas? ( note it does seem to load the SQLLite3  
library - which is in /lib/bin/ because an db, if empty, is created  
before I get an exception)
