v2, 2 partsWorkaround for iconv under macOS 14/15

From: Torsten Bögershausen <tboegi@web.de>

Changes since v1:
  Re-fined commit message (thanks René)
  Installed a fresh Fink. It lives under /opt/sw now (/sw in older versions)
  However, people can choose other places, I did use the default.
  Make more clear that libiconv from Homebrew, Macports or Fink can be used.
