That message looks familiar to me ;-)

Well, anyway, it means that instead of a real system file handle, you are using a faked one, usually something derived from Tie::Handle that is not connected to a real file. Tied file handles work fine as long as you stay inside the Perl process but you can not pass them to new processes because they do not exists at the operative system level.
