The Intel Fortran compiler needs to be installed. The 2010 release of Marc/Mentat relies on Intel Fortran 10.1(_18)! The 2011/2012 release of Marc/Mentat relies on Intel Fortran 12.0! Make sure that ifort (the compiler executable) is in the PATH and that LD_LIBRARY_PATH is set correctly, refer to the Intel installation guide for instructions on how to do this.
Add acml path to LD_LIBRARY_PATH, to do so either use the script setup_shellrc.py in the installstion folder or for a systemwide setup edit /etc/csh.cshrc.local and/or /etc/bash.bashrc.local.
Assuming ACML is installed in path ACMLDIR the path should read: /ACMLDIR/ifort64_mp/lib (this is the version using paralllization, ie openmp):
for bash: LD_LIBRARY_PATH="/ACMLDIR/ifort64_mp/lib:${LD_LIBRARY_PATH}"; export LD_LIBRARY_PATH
for csh: setenv LD_LIBRARY_PATH /ACMLDIR/ifort64_mp/lib:${LD_LIBRARY_PATH}
As the apply_DAMASK_modifications script has to fix the path for the BLAS it needs to be installed in a place that can be accessed by all users of the system. In addition you have to specify the respective locations in DAMASK_ROOT/lib/pathInfo.
