Graham: Thank you so much for all your help!!
I am not sure exactly how I cleared up the problem. I ran apache under gdb and could not reproduce the error. I have successfully run the test application on Mac OS X Leopard! I also have built a Fedora server as a backup in case this installation does not function again.
