Just for fun, I downloaded and installed it. It installed ok, but it missed one of the prereqs, Parallel::ForkManager. It failed 10/44 test programs and 5/157 subtests failed. I ran the programs in the bin---fear, fear-recorder, and fearperl---none of them worked. The problem was "could not  vf_load '/fear' at /path/to/Fear/API.pm line 889".

What I don't understand is why the author would put all that time into the module and then not iron out the bugs? I can see why it was BACKPANed.
