Crossroads can import it, but only from Pov-Ray version 2.2. If you can find some way to convert it from 3.5 to 2.2, it would work. Crossroads is the only one that I know of.

Edit:
Just out of curiosity, I tried to import a Pov-Ray 3.5 file into crossroads. It wouldn't load at first until I opened the file with note pad and deleted any reference to my custom Header file. After that it was able to import. I then saved it as a 3DS file then imported that back into AC3D. It imported fine, but with one strange anomaly, the colors were transparent. As far as the mesh goes, it was fine. This was a Pov file that was created with AC3D. I don't know how it would work with a standard Pov file. It would be worth a shot to try.
