Someone else responded in the blenderartist.org forum:

"Maybe I am over simplifying, or maybe there is something I am missing here with how you are looking at cycles, but Blender 2.69 can import a DAZ or Poser scene as an obj and the materials and textures are now imported with it.
Granted it is still not perfect because there is tweaking that needs to be done to the materials diffuse levels, reflection maps set too strong, etc. However, at the top center of blender you can change the option from Blender Render to Cycles Render and it works just fine. "

Is that true? We don't really need that script at all?
