When missing gperf, the redirection generates an empty file, which must be manually removed after gperf has been installed. This is difficult to diagnose, as the produced build error is cryptic. Use --output-file of gperf instead to avoid creating an empty file if gperf is missing. This still requires the user to re-run ./configure after installing gperf, though.
