I started over and used macports to install libusb. I made sure to have the following:
$ port installed | grep libusb
 libusb @1.0.18_0 (active)
  libusb-compat @0.1.5_0 (active)
  libusb-legacy @0.1.12_4 (active)

I was using brew before and now have the following:
$ brew list
autoconf automake sdl

I pulled libdc1394.2.2.2 from the following url as the latest version listed on source forge has 2.2.1 listed:

I have made progress as the output is now that no cameras are found! So I think that issue is resolved.
$ ./helloworld 
libdc1394 error: No cameras found

I now need to dig up another camera as the one I was using is not showing up for some reason. So I donít know if it is the camera or still libdc1394 not working properly. I tried the otool command listed and did not get the same results:
$ otool -L ./helloworld
./helloworld: is not an object file

I am not sure why that could be the case. Any suggestions? I am attaching the last few lines from the output of configure, make, and make install.

$ ./configure
