I am fairly sure there is a radio box somewhere in the install process that says "Use head node to compute". I will try and see if I can find it if I can find a computer I don't mind breaking... Don't want to mess with my production cluster, at least one of the installer steps does things even if you hit cancel :)
If you just need to use lam (or I assume mpich, never tried installing that one), it is quite easy to install stand alone and configure to run on one computer. OSCAR is mainly handy for installing the scheduler and resource managers. Then you could go back and start over with OSCAR once you get some compute nodes. Just a thought for a quick fix. Unless there is something else in OSCAR you would need for development, I can't think of anything off the top of my head though. I could walk you through using lam on just one node if you need a hand, I have done it before while testing things.
