scipy (and also math/py-numpy) has fortran in MODULES.
infrastructure/mk/fortran.port.mk does
MODFORTRAN_COMPILER ?= gfortran
MODULES += gcc4
MODGCC4_LANGS += fortran
lang/gcc/8/gcc4.port.mk does
# Always include support for this
MODGCC4_LANGS += c
The result is
$ cd /usr/ports/math/py-scipy
$ make show=MODGCC4_LANGS
fortran c
The port uses gcc for both Fortran and C. I can't change the C
compiler from gcc to clang, because I need gfortran. I wouldn't
change the C++ compiler from clang to gcc, because gcc's libestdc++
might conflict with clang's libc++.
