Failing to load libtbbmalloc.2.dylib

Summary:

In a fresh installation of rstan, linking the libtbbmalloc.2.dylib fails when running the example code.

Description:

A couple of months ago I had a project involving Rstan running smoothly. Returning now, I come across the error stated below. I have uninstalled Rstan, made sure that all dependencies and tool chains are properly installed, and reinstalled Rstan. The problem persists: when using the test code from the Getting Started guide

example(stan_model, package = "rstan", run.dontrun = TRUE)

I receive the error:

Error in dyn.load(libLFile) : 
  unable to load shared object '/var/folders/86/8s8l46dj1h12jrx1m71jkxtn0s352c/T//Rtmpz0AKh0/file6556344933ec.so':
  dlopen(/var/folders/86/8s8l46dj1h12jrx1m71jkxtn0s352c/T//Rtmpz0AKh0/file6556344933ec.so, 6): Library not loaded: @rpath/libtbbmalloc.2.dylib
  Referenced from: /usr/local/opt/tbb/lib/libtbbmalloc_proxy.2.dylib
  Reason: image not found

Package RcppParallel is installed (see session info below).

Reproducible Steps:

remove.packages('rstan')
# Restart R session
install.packages("rstan", repos = "https://cloud.r-project.org/", dependencies = TRUE)
example(stan_model, package = "rstan", run.dontrun = TRUE)

Current Output:

Error in dyn.load(libLFile) : 
  unable to load shared object '/var/folders/86/8s8l46dj1h12jrx1m71jkxtn0s352c/T//Rtmpz0AKh0/file6556344933ec.so':

  Referenced from: /usr/local/opt/tbb/lib/libtbbmalloc_proxy.2.dylib
  Reason: image not found

Expected Output:

A successfully sampled example model.

Reproduce the failure with the documented rstan example and the supplied reinstall steps on macOS Big Sur, then inspect the RcppParallel/TBB dynamic-library linkage shown in the error and session information. Done means the example loads its shared object and successfully samples the example model.
