The short-term workaround is not use gfortran11, which we don't yet support.
Or, if you can wait a few days, there should be an update posted soon that
will provide such support.

Even gfortran10 support (on OSX) has a minor problem, which we are also
trying to get fixed. This only affects some NAB programs, and doesn't break
the build, so most users would not be affected. Finally, if users have
XCode version 12.5 (just released a couple of weeks ago), there is an
additional complication with gfortran10.

But for full OSX support, you need to use a gfortran lower than 10 or 11, as
we note on the installation web page:

[Aside, for OSX junkies: The above advice pertains to gfortran releases
from For me,
using gfortran10 from macports, along with clang from Apple, is OK. I've
not used homebrew myself, but some people have said it's OK.]
