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:

Inizia riproducendo il malfunzionamento della libreria condivisa con il comando dell’installer e ispeziona il codice dell’installer intorno alle posizioni run e main segnalate (righe 552 e 919). Il lavoro è completato quando l’installer termina correttamente usando Python con una shared libpython3.so trovata tramite il suo percorso di ricerca a runtime.
