This locker object is uses File::FcntlLock, and was contributed by Jim in Aus. It is close to Mail::Box::Locker::POSIX, but does work on more systems, for instance Darwin.
You will need to install File::FcntlLock separately: there is no dependency to it by the MailBox distribution.

Fatal error: the specific package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package.
To check whether the filename is used to flock a folder, the file must be opened. Apparently this fails, which does not mean that the folder is locked neither that it is unlocked.
For FcntlLock style locking, a folder it must be opened, which does not succeed for the specified reason.
Tried to lock the folder, but it did not succeed. The error code received from the OS indicates that it will not succeed ever, so we do not need to try again.
