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.

Installing Poetry (1.2.2): An error occurred. Removing partial environment.
Poetry installation failed.
See /home/wglenn/git/python/poetry-installer-error-t8owbf6b.log for error logs.

The log:

$ cat /home/wglenn/git/python/poetry-installer-error-t8owbf6b.log
/home/wglenn/.local/share/pypoetry/venv/bin/python3.11: error while loading shared libraries: libpython3.11.so.1.0: cannot open shared object file: No such file or directory

Traceback:

  File "<stdin>", line 552, in run

Beginne damit, den Fehler der Shared Library mit dem Installer-Befehl zu reproduzieren, und untersuche den Installer-Code rund um die gemeldeten run- und main-Stellen (Zeilen 552 und 919). Als erledigt gilt dies, wenn der Installer erfolgreich abgeschlossen wird, sobald Python eine über seinen Laufzeit-Suchpfad gefundene shared libpython3.so verwendet.
