In the shell:

PATH=/opt/gfortran/bin:$PATH R CMD INSTALL ...

in R if using install.packages()

Sys.setenv(PATH=paste0("/opt/gfortran/bin:", Sys.getenv("PATH")))

I found several pages with differing instructions.  I found one in "support.apple.com" that recommended something that didn't work.[2]

I did "env" to get the current path, than appended ":/opt/gfortran/bin" to that and executed the revised "PATH=...:/opt/gfortran/bin export PATH".  However, when I checked with "env" again, the change was not displayed.  I rebooted with the same result.
