Default Executing "las" stand-alone

I am trying to perform test sieving by executing the las program by passing the parameters in the command line.

The output file, which contains the command line syntax, provides no clues.
Code:
# () ./las -v -poly 732541-47.txt -out 20M.txt -I 16 -q0 20000000 -nq 5000 -sqside 0 -lim0 536000000 -lim1 536000000 -lpb0 33 -lpb1 33 -mfb0 66 -mfb1 96 -fb1 732541-47.txt

The poly file and fb1 are the same file. Both which needs to be provided, apparently.

The only clue I get is in stdout to the console.
Code:
# fb_read: prime is not an integer on line 1
I have no idea what needs to be corrected.
