It's a server, you get root access and an IP address.  Buying or 
reusing a domain name and mapping it in DNS is up to you, it's not 
part of the deal.

We last built SWI-Prolog on one one of these thus:

as root:

yum install \
   gcc \
   make \
   autoconf \
   chrpath \
   libunwind \
   freetype-devel \
   gmp-devel \
   java-1.6.0-openjdk-devel \
   jpackage-utils \
   libICE-devel \
   libjpeg-devel \
   libSM-devel \
   libX11-devel \
   libXaw-devel \
   libXext-devel \
   libXft-devel \
   libXinerama-devel \
   libXmu-devel \
   libXpm-devel \
   libXrender-devel \
   libXt-devel \
   ncurses-devel \
   openssl-devel \
   pkgconfig \
   readline-devel \
   unixODBC-devel \
   zlib-devel

then as an unprivileged user:

   wget http://www.swi-prolog.org/download/stable/src/pl-6.2.3.tar.gz

   tar zxf pl-6.2.3.tar.gz

   cd pl-6.2.3

   ./build.templ

but you could also do e.g.

   yum install git
   git clone git://www.swi-prolog.org/home/pl/git/pl-devel.git
   cd pl-devel
   ./prepare
   ./build.templ
