Thanks for your answer,
Based on your suggestion I re-installed the amber10 and this time I patched the bugfix.all.
When I run it, the first problem ( mdfil: Error unknown flag: -y ) is still here. This is to say I still did not compile correctly?
Thanks for your help again!

Also, do not put mpirun -np 4 before MMPBSA.py. You do not want to
start 4 threads of this process (since MMPBSA.py itself uses "mpi_cmd"
inside the script, you'll wind up with 16 threads on this node, all of
which will be overwriting each other and in general causing chaos!).
For the rest of the issues, see Bill's email.
