GNU parallel produces nonsensical error messages and aborts

[David Kastrup]

Just executing

parallel

on its own leads to the error message

parallel: Error: -g has been retired. Use --group.
parallel: Error: -B has been retired. Use --bf.
parallel: Error: -T has been retired. Use --tty.
parallel: Error: -U has been retired. Use --er.
parallel: Error: -W has been retired. Use --wd.
parallel: Error: -Y has been retired. Use --shebang.
parallel: Error: -H has been retired. Use --halt.
parallel: Error: --tollef has been retired. Use -u -q --arg-sep -- and --load for -l.

and parallel aborting. This looks rather absurd. As parallel appears to be a perl script, I suspect a perl version mismatch.

It could also be caused by http://stackoverflow.com/questions/16448887/gnu-parallel-not-working-at-all in which case it is easily solved by removing --tollef from any config file.
