OK: you have to fix this, then re-run makeDIST_RST.

Please update to the current version of AmberTools. Or, please post your
prmtop and P1.x files, and we'll try to figure out why ambpdb is failing.
You can also use savePdb inside LEaP to create a pdb file. (If you do wnat
to upload your files, please indicate which version of AmberTools you are
using.)
