I suppose that the Rhino uses UV-mapping in its meshes and that it saves
it in its file format (whichever it is). The converter you are using to
convert the mesh to POV-Ray format needs to be able to convert the UV
information as well.
One possibility, as already suggested, is to use bicubic patches instead
(but you have to create them by hand or with a program like Hamapatch).
The advantage of a bicubic patch is that you can map a texture on the
patch; the UV-coordinates are calculated by POV-Ray automatically so you
don't need to do it yourself.
