Was it the Homebrew build of gfortran, or the one from
<https://mac.r-project.org/tools/>? Does this happen if you run R CMD
build <path> in the Terminal instead of devtools::build()?

It might be that you need this specific R.home('etc')build, or you
might have to adjust some paths in file.path(R.home('etc'),
'Makeconf'). A different build of gfortran may be not compatible with
the one used to compile R.

If you don't get a useful answer here, consider asking at
R-SIG-Mac using r-project.org, because this seems to be a Mac-specific
problem.
