SOLVED Re: help compiling USER-MOLFILE

Solved problem. I now understand that the plugin I need is the
pdbplugin.so shipped with VMD.
Also the dump command needs to be:

dump dump1 all molfile 1000 dump-*.pdb pdb
/path-to-vmd-install/plugins/../molfile/

nothing else is really needed to be edited on the lammps side.
