This kind of error typically occurs when something is compiled with a
newer version of GCC/glibc and then linked with an older version. Do you
happen to have a gcc or gcc-toolchain installed in your profile (and
does removing it solve this issue)?

Alternatively, you could try

  guix environment --pure --ad-hoc r-rstan r-rstanarm r bash coreutils

(Using --pure prevents packages from your profile being used.)
