Just ignore this message, but make sure you load the file BEFORE
you load your pdb file. To check the unit loaded okay you can enter

edit CL3

This should bring up the CHCl3 molecule in the edit window.
You can then load the relevant leaprc.gaff, leaprc.ff03 frcmod.chcl3 and
then finally your pdb file. The CL3 residue should then be recognised. If it
isn't check the names of the atoms in the CL3 residue in your pdb file they
should match those in the file - namely H1, C1, CL1, CL2, CL3 - if
they don't then you will need to edit your pdb file such that the atom names

I hope this helps.
All the best
