Ack! I try to avoid compiling as much as possible. I realize that this goes against the whole Open Source thing, but I find .rpm's to be WAY easier.
Grab the .rpm version
here and then use kpackage, or one of the other package programs (on KDE, hit the K button, choose applications, and they should be in there somewhere, I can't recall where exactly). On 'drake 7.2 there's four to choose from, kpackage works pretty well. I wish I was at home, I could talk you through it directly. An .rpm is a basically like using the Windows install, it unpacks everything and put's it all in the right spot. It also checks for problems relating to things interfering with each other - which is a big improvement over Windows which will just install and you'll find out that something's hosed later when you start bluescreening. This is a pretty painless way to do it.
If kpackage doesn't cut it (for whatever reasons), then open up a terminal window (third or fourth icon from the left on the bottom, IIRC), and type the instructions
here under the heading: Using the Source RPM Package.
Like I said, feel free to call me. It being a holiday of sorts, there's practically no one here and my workload is pretty light today.
