This is almost certainly because your implementation of lam was compiled
with a different compiler to the one you are using to compile amber. Likely
Lam was compiled with g77 and you are using ifort for amber. Get hold of the
source code for lam and build it yourself specifying ifort as the fortran 77
and fortran 90 compiler. Then make sure this directory is first in your path
(so you pick up the correct mpf77 and mpirun) and set LAMHOME to point to
this directory.
Then make sure you do a make clean in the amber source directory and then
try compiling it again.
All the best
Ross
