Take a look at the other force field files in the same directory. What files are there (.rtp, .atp, .hdb, etc)? You are still missing a lot of files. Search the mailing list archive for charmm; I recall seeing a few posts regarding where to download the necessary components, but I have never used them so I can't help much more than that.
