installation errors

Actually, it seems like the install went fine.  The first half anyway.  I put the address of my elgg installation in the browser and pointed it there.  That worked fine.

I put my username, database password, database name in and hit save.  That worked fine.

Then, I filled out that information.  I put the name of the community and my email.  I put in the correct paths and filled out the rest.  When I hit save, I got an http - 500 Internal Server Error

"The Page Your Are Attempting to Load Returned an Error"

It's taking me here: action/systemsettings/install

So, I started troubleshooting.  One thing I noted is that when you download the elgg zip file and open it up, it comes with an "actions" folder that has a systemsettings folder in it with the file install.php inside.  Is that where it's directing me?  Is that the issue?  Or is this a mute point and my problem is something entirely different?
