Some of the optimization flags look like they may be ifort-specific (i.e.
-xP and/or -ip, and I've never seen -tpp7).

I would suggest using mpif90 instead of gfortran, just make sure that mpif90
comes from the (working) MPI you want to use, and that it wraps the gfortran
compiler (mpif90 -show will help you here).

-lsvml is, I'm quite sure, an intel compiler specific library. As is -limf.
And IFORT_RPATH basically confirms that you attempted to hijack the ifort
config_data file and didn't really make any changes. Different compilers
have different flags that they use.

I would not imagine the above would work, but you have to be more specific.
First of all, you created the file with .lam on the end, but didn't define
any MPI variables (i.e. MPI_DEFINES), etc. Also, like I said, it looks like
you just changed ifort to gfortran and didn't change any of the
ifort-specific flags.
I've attached a config.h file that you can use (so you do not need to run
the configure script). This should work as long as you have a working MPI
in which the mpif90 works. Place this in $AMBERHOME/src/pmemd and make sure
that $MPI_HOME is set appropriately, then run make install in that
directory.
All the best,
Jason
