I downloaded a program that needed to be compiled to be used, and I'm trying to teach myself the process. The first problem I had when I ran a ./configure was missing SDL 1.2. I downloaded it, but when I try to run it, I'm instructed to run ./configure, then make, then make install. I got through the first two steps, and the third told me permission denied (i'm the only user). I repaired permissions, and then tried again, and the same problem cropped up, only on the second step. Help! This is all in Terminal on OSX 10.4.10.
