I installed RT at work a couple days ago using pkgsrc. This was the first time I'd ever used pkgsrc, and I have to say I'm impressed. Yes, it's just like a portable ports tree — but it's just like a portable ports tree, and I'm starting to think that's a very, very powerful idea.
RT went well except for the final install, where it complained and died. Fortunately, it turned out to be susceptible to exactly the sort of one-line patch that I have an affinity for. Not as cool as correcting Theo de Raadt's code, mind you :-) but still a good feeling.
Ah...RT, I've missed you.
