OpenBSD 3.7 and installing packages

I'm a Unix noob and I want to learn Unix, so I fired up Vmware and installed OpenBSD on it. Now I am trying to install packages, like links, w3m, and naim. But, being a newb, I am hitting problems.

For Links, I've extracted the tar and now I have a folder with a bunch of C files. I run ./configure which runs fine, then make, which gives me an error saying "previous declaration of strtonum" in the stdlib.h file.

For Naim, I can't get it to even extract. It is a tar.bz2. Above on the tar.gz I used gunzip then tar -xvf, but those won't work on Naim.

Does anyone know how to do these things? Thanks for any help.

First, lynx should be installed from the openbsd install, so there should be no need to install it separately.

Incidentally, you should really install from OpenBSD's package or ports mechanisms. Why? Because these apply patches if necessary, to make the programs compile under OpenBSD. Also, they install all dependencies automatically and save you a lot of work. See http://www.openbsd.org/ports.html for more.

To unzip a *.bz2 archive file, you need to install the bzip2 package first, which you can install either from packages or ports. Then do a
bzip2 -d package.tar.bz2
This will un-bzip it to package.tar
Then do a:
tar xvf package.tar
to untar the package.
