Might be an idea to try a search (http://www.gromacs.org/external/search.html) of the emailing list when you get errors like this. This is a very common one and a significant number of responses are available on the list, archived for future reference.
Quick word on what the issue is, pdb2gmx is for generating the topology files for proteins. PDB file has to have the residues named corrently to the names used in the database of residues (corresponding to the forcefield used). If you don't have proteins, then you don't use pdb2gmx. You have to generate the topology file yourself, and how you do this is covered in the manual. Plus try searching on this emailing list, has been covered many times in great detail.
