Trouble with PhoneGap demo: "nothing to be done for..."

I'm trying to do the PhoneGap demo for IOS at:

http://mobile.tutsplus.com/tutorials/phonegap/phonegap-development/

It says t开发者_运维百科o open a terminal in the folder that has "PhoneGapLibInstaller.pkg". I did that. If I do "ls", I can see the file listed. Then it says to run "make". I'm not a terminal person very much, but it first said "make: * No targets specified and no makefile found. Stop." I assumed the tutorial left out the file name so I tried "make PhoneGapLibInstaller.pkg". Now I get "make: Nothing to be done for `PhoneGapLibInstaller.pkg'."

What should I be typing?? I wish tutorials would be more clear sometimes :)

Have you tried following the install instructions on the PhoneGap Wiki for iOS?
