"too many arguments" during raccheck execution

Hello there,
I executed the raccheck utility on "Enterprise Linux Enterprise Linux Server release 5.1 (Carthage)" x86-64
./raccheck -a

and got failures similar to that:

Is there something should be installed additionally, or OS not supported or something else?


Thanks,
Andrey
