Comment (by chrstphrchvz):

 I don't see in rpy2 source code where it uses OpenMP, so I'm not sure
 whether it should be forced to use an OpenMP-capable compiler (by setting
 `compiler.openmp_version`). I wonder if this is due to the `+openmp`
 variant recently added and made default in the `R` port (#61256) and if
 that is leaving behind `-fopenmp` as a flag for R extensions to compile
 with (possibly assuming that extensions will be compiled using the same
 compiler as R itself).
