migrating MacPorts to High Sierra: "All compilers are either blacklisted or unavailable..."

[Murray Eisenberg]

On the other hand, I can manually restore at least some ports, e.g.:

  apache-ant @1.10.1_0 (active)
  bzip2 @1.0.6_0 (active)
  cctools @895_4+llvm40 (active)
  expat @2.2.5_0 (active)
  gcc7 @7.2.0_0 (active)
  gcc_select @0.1_8 (active)
  gettext @0.19.8.1_0 (active)
  gmp @6.1.2_1 (active)
  isl @0.18_0 (active)
  ld64 @3_0 (active)
  ld64-latest @274.2_1+llvm40 (active)
  libcxx @3.9.1_0+universal (active)
  libedit @20170329-3.1_2 (active)
  libffi @3.2.1_0 (active)
  libgcc @7.2.0_1 (active)
  libiconv @1.15_0 (active)
  libmpc @1.0.3_0 (active)
  libxml2 @2.9.7_0 (active)
  llvm-4.0 @4.0.1_2 (active)
  llvm_select @2_0 (active)
  mpfr @3.1.6_0 (active)
  ncurses @6.0-20170916_0 (active)
  openssl @1.0.2m_0 (active)
  xar @1.6.1_0 (active)
  xz @5.2.3_0 (active)
  zlib @1.2.11_0 (active)

Is something wrong with the restore_ports.tcl script? (I did newly download the version (0.1) that I used via:
  curl --location --remote-name https://github.com/macports/macports-contrib/raw/master/restore_ports/restore_ports.tcl
