Is there something in specific that we can help with?
for a text prompt, you will want to run at runlevel 3.
at the command line, type su(to logon as the superuser) and enter the root passwd. then type /sbin/init 3
generally there are a few common ways that devs package software. As an rpm, or a tarball.
you can find more on there installation here.
a tarball is a bit different, but it is a personal choice. i know there was an omp around here somewhere for those. maybe you wouldn't mind finding it for me since i have to go to class :P
