Thanks for the help Walter.
Once I got all the 386 libraries installed, the command works from the
command line.
Now the website just tells me to "Please try again later. System busy,
Could not gain access to the counter file."
The counter file is just a 4 character file in the cgi-bin directory
with full rw-rw-rw permissions. So I've made a lot of progress just by
being able to type the command line "fpcgi" without errors.

In the past, I've found that setting the permissions properly was critical, but it's been so long since I had to configure this, I really need some help. I've looked at permissions from other openserver systems, but it doesn't seem to help.
