:debug:configure     while executing

However this succeeds:

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

sergey-fedorovs-powerbook-g4-12:~ svacchanda$ port -v installed
The following ports are currently installed:
  R @4.1.2_1+builtin_lapack+cairo+gcc7+openmp+recommended+x11 (active) requested_variants='' platform='darwin 8' archs='ppc' date='2022-02-15T10:14:40+0800'

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

I think the problem is that MacPorts base has not put any compilers into the list of possible compilers. I don't know why.

The same problem was reported for poppler in #64750 however the cause there may be different.
