Actually the package contains some custom message files,which are created only when we build the package. So here in this case we can see that different errors come while building at different times which means that each time we build ,some of the custom message files are created and hence once all the custom message files are created ,there is no build error.

So the simple thing that can be done in such cases is to build again and again and eventually you get no such errors.
