Code Signing Difficulties

Still getting the “resource fork, Finder Information or other detritus not allowed” error when attempting to code sign with AppWrapper. Found this article at Developer.Apple.com which was enlightening.
Running the “xattr -cr” command on the pkg pre-signing had no effect on the error message.
Here is a small portion of the output I received when running the "$ xattr -lr " command. This output seems to suggest that there is the prohibited Finder Information within the Frameworks/IDEUtils.dylib and others. If this were the case, it seems that every developer here would be having this problem when signing under Sierra. Can anyone provide some enlightenment for me?

I did the xattr -rc on the app file itself

xattr -rc 'My App.app'
