Oh wow so this is like 2002 gentoo then?
Generally Arch doesn't install something until you ask it to.
I started back at about Redhat 5.0, used a lot of distros over the years, currently I use ubuntu because it 'mostly worked' from install, although it didn't really. I've ended up doing make/make install a few times for packages I needed configured like I wanted them. I might go back to Slackware when I get around to it, not really a big fan of Ubuntu at this point for what I do (programming).
