Atom names within a residue must be unique. Looks like all your carbons
are named "C", etc. (Also looks like you are missing most hydrogens...be sure
to check that. You'll have to add hydrogens before make the library mentioned
in the next paragraph.)

Even if the atom names were made to be unique, you can't just pass a pdb file
with an arbitrary ligand to tleap. You have to create an Amber library for
that first. See tutorial B4 for an example of how this is done.
