Okay,
So, in the manual under
SetObjectMeshImage( objID, meshIndex, imageID, textureStage ) , it says that ...
"Texture stages can be used to assign multiple images to a mesh, for example you might put the base (diffuse) texture in stage 0, a normal map in stage 1, and a light map in stage 2. "
And, when trying to set the Normal map as stage 1 and the light map as stage 2 as per the instructions, I could not get it to work right.
Then, when looking at the manual under
SetObjectNormalMap( objID, imageID ) , it says ...
" The normal map will be placed in texture stage 2, overwriting anything that is already there and will have a shader generated that combines it with any dynamic lighting, to correctly light the object."
So, i used that command and actually got a bump happening with the built in shader!
So, I changed my SetObjectMeshImage stages to Diffuse to 0, Normal to 2 (using the other command), and Specular to 1, and got better results.
If you just want to see the bump, then don't use the specular, because I may still be using it wrong.
I had a couple requests for the code to this simple model viewer, so here is the revised code if anyone want to play around with modifying it...

You can ignore that object_num because I had plans to be able to load multiple objects at the same time, but haven't gotten that far yet.
Anyway, I hope this helps, and have fun.
EDIT
I had some old comments and code that was commented out that did not apply which I accidentally left in the first post of the code.
So, I just edited the post to remove those unnecessary sections of code to make it a bit cleaner. (sorry about that sloppy code/post)
