I'm building with synth.
jrmarino says this should work,
i.e. the problem is not in synth.

I have DEFAULT_VERSIONS=gcc=8 in synth make.conf:

# cat /usr/local/etc/synth/LiveSystem-make.conf 
DEVELOPER=yes
FFLAGS+= -O2 -pipe -march=bdver2 -mtune=bdver2
FFLAGS+= -funroll-loops --param max-unroll-times=4 -ftree-vectorize
FFLAGS+= -g
DEFAULT_VERSIONS=gcc=8

However, when building net/mpich, gfortran7 is used:

--------------------------------------------------
--  CONFIGURE_ENV
--------------------------------------------------
PKG_CONFIG=pkgconf
F77="gfortran7"
FC="gfortran7"

Here's the full log:

https://seis.bristol.ac.uk/%7Emexas/net___mpich.log

Should setting DEFAULT_VERSIONS=gcc=8 in make.conf
be sufficient to force the use of gfortran8?

Looking at /usr/ports/Mk/Uses/fortran.mk, my answer is yes.

Please help
