Initialization failure in MacOS + homebrew + pyenv

[camlspotter]

Under MacOS + homebrew + pyenv, I fail to initialize pyml:

let () = Py.initialize () fails with the following error message:

% pyenv local 3.10.9
% dune exec ./mytest.exe
Entering directory '/Users/jun/pyml'
Done: 60% (3/5, 2 left) (jobs: 0)Fatal error: exception Failure("Py.find_library: unable to find the Python library [libpython3.10m.dylib returned dlopen(libpython3.10m.dylib, 0x0009): tried: 'libpython3.10m.dylib' (no such file), '/usr/local/lib/libpython3.10m.dylib' (no such file), '/usr/lib/libpython3.10m.dylib' (no such file), '/Users/jun/pyml/mytest/libpython3.10m.dylib' (no such file)] [/opt/homebrew/lib/libpython3.10m.dylib returned dlopen(/opt/homebrew/lib/libpython3.10m.dylib, 0x0009): tried: '/opt/homebrew/lib/libpython3.10m.dylib' (no such file)] [libpython3.10.dylib returned dlopen(libpython3.10.dylib, 0x0009): tried: 'libpython3.10.dylib' (no such file), '/usr/local/lib/libpython3.10.dylib' (no such file), '/usr/lib/libpython3.10.dylib' (no such file), '/Users/jun/pyml/mytest/libpython3.10.dylib' (no such file)] [/opt/homebrew/lib/libpython3.10.dylib returned dlopen(/opt/homebrew/lib/libpython3.10.dylib, 0x0009): tried: '/opt/homebrew/lib/libpython3.10.dylib' (no such file)]")

The library to be found, libpython3.10.dynlib is at$HOME/.pyenv//versions/3.10.9/lib/libpython3.10.dylib, but pyml cannot find it. It executes python-config --ldflags to locate the library directory but under my environment, MacOS + homebrew + pyenv, it prints something unexpected for pyml:

% python-config --ldflags
-lintl -ldl -L/opt/homebrew/lib -Wl,-rpath,/opt/homebrew/lib -framework CoreFoundation

FYI, I use the following quick fix to locate the correct directory $HOME/.pyenv/versinos/3.10.9/lib by executing python-config --prefix instead of python-config --ldflags: https://gitlab.com/dailambda/pyml/-/commit/b09f7160dd232eba5784f8553e44ea86d8ddbdda (Sorry this is not GitHub but GitLab).

Thanks a lot for the report and sorry for the delay. This should be fixed now.
