prodikal,
There are two ways to install netcat :

1. install netcat from http://freshmeat.net/projects/netcat/?topic_id=150 and then apply this path http://www.reza.net/rio/nc110-patch and then just compile it using this command :
# make linux CC=arm-linux-gcc DFLAGS=-DGAPING_SECURITY_HOLE

2. The easy way (is this the one you asking for ?) just download this "netcat binary" http://www.reza.net/rio/rc

I hope this helps..

Cheeerss

BTW..have you solved your problem about sawfish??
