I hate to be all cliché with yet another "best [something]" question, but I am genuinely interested in what you most often install with MacPorts. When you get a new Mac, which ports do you first install?
So far, I've installed wget and watch, since I find those to be very useful on Linux machines. I also installed wine and winetricks to run a Windows program or two. And earlier today I started playing with Scala, so I installed the scala28 port.
Tip: to see your installed ports, use the port installed
command.
