Thanks for your reply.

Here is what I have added to .bashrc:

LD_LIBRARY_PATH="/opt/mopac/MOPAC2012.exe:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH
alias mopac='/opt/mopac/MOPAC2012.exe'

This was suggested by Jimmy Stewart, the MOPAC author and maintainer.

This works in Debian 8.00 that I'm also running in another VM on my 
laptop as a test bed before updating my main Linux computer.-- Stephen
