Error when trying to install BioGeoBears package dependency rexpokit no longer on CRAN and won't install

Question

I am trying to install the R package rexpokit which is a dependency for BioGeoBears. The CRAN version of the package was just removed on Oct 10, 2023.

I tried downloading and installing from the archive, but when I try to install the package I receive this error code:

* installing *source* package ‘rexpokit’ ...
** using staged installation
** libs
/opt/R/arm64/bin/gfortran -mtune=native -fno-optimize-sibling-calls  -fPIC  -Wall -g -O2  -c lapack/blas_mod.f -o lapack/blas_mod.o
make: /opt/R/arm64/bin/gfortran: No such file or directory
make: *** [lapack/blas_mod.o] Error 1

Has anyone else had luck with a back door way of installing this package for BioGeoBears?

Answer 1

You're missing a fortran compiler. Please go through the dedicated section at CRAN for macOS https://mac.r-project.org/tools/, do everything they instruct, and please come back if none of that solves the problem.
