I replaced the line 
(NSString*) launchPathForTool: (NSString*)DPSetBit0;
with (used instead of NSTool the NSTask method): 

[DPSetBit0 setLaunchPath: [NSTask launchPathForTool: @"DPSetBit0"]];

I shall use methods you adviced to me for OS X using:

 #ifdef __APPLE__
   // get a list of the directories the program might be in
   // NSSearchPathForDirectoriesInDomains()
   // append your program name to each directory in turn
   // [NSString-stringByAppendingPathComponent:]
   // check each to see if the program is there
   // [NSFileManager-isExecutableFileAtPath:]
 #endif /*  __APPLE__ */

but first I must study these methods so I can use these too.

Any advices will be appreciated regarding this task.
