I’m attempting to install the copula package along with its dependencies in R version 4.0.2 on MacOS, but I’m encountering multiple errors related to the compilation of dependencies. Here is what I’ve tried:
install.packages(“copula”)

I chose to install from sources when prompted. However, the process fails with errors during the compilation of Matrix, gsl, mvtnorm, and pcaPP. The key issues include:

For Matrix, the error is related to linking with -lgfortran (not found).
For gsl, the configuration fails because gsl-config is not found.
For mvtnorm, the error is related to missing gfortran.
pcaPP and ultimately copula fail due to these unmet dependencies.
Here are excerpts from the error logs:

Matrix and gsl related errors:

ld: library not found for -lgfortran
clang: error: linker command failed with exit code 1
configure: error: gsl-config not found, is GSL installed?

mvtnorm related error:
gfortran: No such file or directory
make: *** [mvt.o] Error 1

Suspect the issues might be related to the absence of certain compilers or paths not being properly configured. How can I resolve these installation issues to successfully install the copula package and its dependencies on MacOS?
