Getting the nc (netcat) command to work in Leopard's Terminal?

I cannot get the nc command to work in the Terminal. I type in a command and it just gives me the syntax for the command.
I have tried to do sudo su and it doesn't make it work either.
The strange thing is is that it worked fine for me on Tiger.
The command i was doing was "nc -vlp port."

MacBook Pro 2.0ghz, Mac OS X (10.5.3), First Gen (I think) MBP

Some of the shell scripts have been changed/updated with Leopard, but the current man pages installed with the OS should also have been changed/updated. If there is a conflict, usually Apple's online Mac OS x Manual Pages reference will have the correct information. Netcat works for me - if you check the current nc man page, you will find that the "l" and "p" options cannot be used together.

Whoops, I think i double posted (I didn't see an edit button for my last post).
I just tested the command that you suggested, and it worked (i think, but it didn't say listening, it just was blank, so i believe it was working). I looked on the man pages and didn't see the -e function and I remember the "new" nc saying "illegal option -e." I was wondering how to send something over to another computer running nc, like a shell.
