A couple comments here. Bugfix.43 for Amber 9 fixes the -y flag, so make
sure that all bug fixes are applied. See
http://ambermd.org/bugfixes90.htmlfor details about the Amber 9 bug
fixes and how to apply them.

As for the AmberTools 12 MMPBSA.py version, you will need to install the
full AmberTools 12 suite in order to take advantage of it (indeed, the
error you're seeing is an unpatched sander issue, not an MMPBSA.py issue).
Note that since AmberTools 12 was released, MMPBSA.py no longer depends on
sander for many of its common analyses. This means that at the very least,
NAB and two NAB programs written with MMPBSA.py need to be compiled in
order to use it.

AmberTools 12 is a free download released as open source, so there is no
financial cost for downloading it. If you are having trouble compiling
AmberTools 12, google your error message to see if the problem has been
resolved in the past. If you still need help, write back to this list with
the exact series of commands you used along with the error messages you got
(simply saying "it doesn't work" provides no help for those of us trying to
diagnose your issue remotely).

HTH,
Jason
