I've long been a user of RcppArmadillo, but have been unable to compile any programs via sourceCpp since upgrading my OS to Monterey Version 12.3.

Getting the following error:

```
ld: malformed universal file: slice content is not mach-o or a static library file '/usr/local/lib/libgfortran.dylib'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [sourceCpp_2.so] Error 1

```

It seems like this has something to do with static vs dynamic linking judging by the post [here](https://gist.github.com/loderunner/b6846dd82967ac048439) but I really have no idea.
