there is no reason to use -gnucompat, but that is probably not your problem.

Failures to compile new2oldparm are almost always symptoms of a failure to
correctly install the compiler. Have you checked that you can compile simple
fortran programs with your version of ifort? The fact that the error message
refers to "gfortran" suggests that some configuration is not correct, but
I don't recognize this symptom (maybe someone else on the list has seen it).

Googling the error message (always a good idea!) suggests a connection to
BLAS. Do you have either the MKL_HOME or GOTO environment variables set?

Also, looking at the entire log of the make (rather than just reporting the
final error) is also highly recommended. Finding the *first* thing that goes
wrong is very often the clue to finding the fix.
