1. Does the main test work? (components-python-test_python.gpr)

2. What are the scenarios, you use when building:

arch
Atomic_Access
Target_OS

Depending on that a version of py-load_python_library.adb is selected
which is responsible for loading the Python library.

This selects py-load_python_library.adb from os/pthread which is just a
copy of os/linux. Likely there are differences between Linux and OSX. If
you have time I could fix it by tracing locations causing the problem on
your target. Mail me, if you want.

dlopen() would need to see e.g.

$FRAMEWORKS/Python.framework/Python/Versions/3.8/lib/libpython3.8.dylib

where $FRAMEWORKS would normally be /Library/Frameworks but, in Roger's
case (running Homebrew), would be $HOMEBREW_PREFIX/Frameworks (Roger
might have frameworks scattered bewtween the two places, for added fun).

Thanks Simon.

Is the variable $FRAMEWORKS set or I have to search a whole set of subdirectories?

It's not set; I'm not sure what the Homebrew version would look like,
but it's probably like /Library/Frameworks. And I left out Current,
which chooses between e.g. 3.8, 3.9.

libpython := '';
find_libpython:
for top in $HOMEBREW_PREFIX/Frameworks, /Library/Frameworks loop
if exists $top/Python then
libpython := $top/Python/Versions/Current/lib/libpython*.dylib;
exit find_libpython;
end if;
end loop find_libpython;
fail if libpython is still ''

There is another macOS package manager, MacPorts, but I've settled on
Homebrew.

I researched a little bit. Mac's Python is even more messy than Windows'
one. That is an achievement of its own! (:-))

So far I come to the list

/usr/lib
/Library/Frameworks/Python.framework/Versions
/sw/lib
/opt/lib
/opt/homebrew/lib

each to be searched recursively for the name:

libpython3.*.dylib

P.S. It seems that I must check Julia bindings as well. So far it looks
so that nobody ever used them on Mac.
