 However this succeeds:

 {{{
 sudo port -v -s install r configure.compiler=macports-gcc-7
 }}}

 {{{

 The following ports are currently installed:
   R @4.1.2_1+builtin_lapack+cairo+gcc7+openmp+recommended+x11 (active)

 }}}

 I guess compiler should be called depending on the OS here without a need
 of a custom line.
