2DGraphics_dbg.app problem

[thesk1llerz]

Hello all,
I am new to this engine and tried to run the Irrlicht engine in Xcode and I'm getting this error any help?
I am not that great of a programmer so all help would be appreciated. If I understood the error I am missing a file, I tried to redownload the engine but that didn't work.
The error message i get is:
"error: There is no SDK with the name or path '/Developer/SDKs/MacOSX10.4u.sdk'"
Thanks for the help in advance
