The error means that your system does not have Intel Fortran Compiler. What you can do now is to implement the Intel compiler (not free) or to use gfortra instead of Intel Fortran Compiler. To use gfortran, you have to edit the "makefile", which is located at your current directory, as follows:

First, comment out the lines
#######################################
# Intel compiler used
# In the case of ifort 16.0.0 or later
#######################################
fort = ifort
flag = -O2 -mcmodel=medium
omp = -qopenmp
nomp = -qopenmp-stubs
#
such that

#######################################
# Intel compiler used
# In the case of ifort 16.0.0 or later
#######################################
#fort = ifort
#flag = -O2 -mcmodel=medium
#omp = -qopenmp
#nomp = -qopenmp-stubs
#

and then uncomment the following lines such that

#######################################
# GNU Fortran compiler used
# In the case of gfortran
#######################################
fort = gfortran
flag = -O2
omp = -fopenmp
nomp =

If this works, your system has "gfortran"
If this again causes errors, you have to install gfortran yourself. It is free software and rather easy to install. If you get any trouble in this stage, you should ask the system administrator.
