Here's what you should do: download AmberTools19 from
That will untar into a folder headed by "amber18". Install and test
that, setting that amber18 directory to be your AMBERHOME.

Then, go back to amber16/pmemd/src/pmemd and type "make install". This
will just make pmemd.MPI. If you cd to $AMBERHOME/test, and type "make
test", you will just be testing the pmemd.MPI code

Finally, put $AMBEHROME/bin in your PATH, and also put pmemd.MPI somewhere
in your PATH (easiest is cp pmemd.MPI $AMERHOME/bin).

Bottom line, you can (and should) use an up-to-date AmberTools along
with the amber16 version of pmemd. (Of course, even easier is to
upgrade to Amber18, but I understand that costs money.)

...hope this helps....dac

p.s. if you see a similar lmod error with AmberTools19, let us know the
details of your compilers and MPI installation.
