Subject: system ( ) call but suppressing =>true

I have a Perl script that takes a command line argument that I'm trying
call from a Ruby (in Rails).

The Perl script needs an IP address on the command line and runs as
follows:

/usr/bin/router.pl 172.21.1.1

The following ruby code works perfectly for what I want but the only
problem is that it returns "=>true" in addition to my data.

I tried formulating a string and putting backquotes on it but couldn't
get that to work. (example `x + y + z`)

Is there any way to make system() suppress =>true?

 x = "/usr/bin/router.pl"
 y = " "
 z = "172.21.1.1"
 system(x + y + z)

thanks again...
