Does not work with a shared libpython3.so on run-time search path

I'm using the CPython configure flags --enable-shared with an rpath interpolation (LDFLAGS). Linux platform (RHEL 8.3).

The interpreter's stdlib venv works just fine, but poetry installer doesn't like something about that config

$ readelf -d /usr/local/bin/python3.11 | grep rpath
 0x000000000000000f (RPATH)              Library rpath: [$ORIGIN/../lib]
$ ldd /usr/local/bin/python3.11 | grep libpython
	libpython3.11.so.1.0 => /usr/local/bin/../lib/libpython3.11.so.1.0 (0x00007ffff7632000)
$ curl -sSL https://install.python-poetry.org | /usr/local/bin/python3.11 -

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

/home/wglenn/.local/bin

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

The log:

Commencez par reproduire l’échec de la bibliothèque partagée avec la commande de l’installateur et examinez le code de l’installateur autour des emplacements run et main signalés (lignes 552 et 919). C’est terminé lorsque l’installateur s’exécute jusqu’au bout avec succès quand Python utilise une shared libpython3.so trouvée via son chemin de recherche à l’exécution.
