Publishing for Mountain Lion, getting errors

Hello, I have upgraded to lion, and problems are occurring. I got no errors before, now I get
warning: There is no dwarfdump executable defined. (-19035)
warning: iPhone/iPod Touch: Unable to extract image dimensions. Please make sure it is a valid PNG image file. (-19014)
warning: iPad: Unable to extract image dimensions. Please make sure it is a valid PNG image file. (-19014)
warning: There is no codesign_wrapper executable. Please reinstall the Xcode developer tools. (-19058)
After all ios builds.

Anyone figured out a solution? [import]uid: 59735 topic_id: 22401 reply_id: 322401[/import]
