So I'm using a modified set of commands (in the attached file) to generate .frcmod and .prepin files for the ligand and then load them before loading the protein. This gives me .prmtop and .inpcrd files for the complex to start my MD jobs. I have used general terms like ligand, protein and complex in the file, just to emphasize that it can be used for any ligand-protein combination and not specific to sustiva case. Regarding the paths I guess you will have to add them into your .bashrc and source it before the changes take effect. I guess this helps...
