<p dir="auto">but no sight of gfortran in /opt/R/arm64/bin</p>
<p dir="auto">so the building of my package fails.</p>

make: *** [chek.o] Error 1</p>
<p dir="auto">Of course, there is a warning on that web page (so why the link to it?) saying that</p>
<p dir="auto">IMPORTANT: All binaries are moving to a unified repository under /bin/darwin<ver>/<arch> with manifest file to simplify automated installataion. Go to /bin/darwin20/arm64 for latest Big Sur arm64 binaries. The following is only kept for legacy access.</p>
<p dir="auto">but there I cannot identify (by name) any file that could contain a fortran compiler.</p>
<p dir="auto">To summarize: I need help.</p>
<p dir="auto">Thanks, Göran</p>
