I agree that the message should be improved. However it is a bit more
complicated for pylint that for ls, since, if no file is found, pylint
tries to find a module on sys.path with the provided name. 

This issue has been added to our tracker[1] and will be fixed in the next
pylint release. Thanks for your bug report.
