problems using the bc package

Hi All,

I am hoping that someone have an answer for this. I have downloaded the bc
package form the following link
http://code.google.com/p/r-bc/

from "on windows" and saved the file under R/library

I am using R form windows vista, when I open R, bc does not appear under
load packages.

I have tried the examples in 
http://www.kingcomputerservices.com/unix_101/using_bc_part_1.htm
 from the command line  an it works fine. the problem occurs when I try to
run the simple example in  http://code.google.com/p/r-bc/ from R in windows

here is what I get

source("http://r-bc.googlecode.com/svn/trunk/R/bc.R") 
one <- bc(1) 

Error in system(cmd, input = input, intern = TRUE) : -l not found

thanks for your help
