Can't call Python from Rust with pyenv

OS: PopOs (Ubuntu) 22.04
System Python: python3 3.10

Steps:

PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.9.16
pyenv virtualenv 3.9.16 test
pyenv activate test
cargo run

Output:

     Running `target/debug/noos-serve`
target/debug/noos-serve: error while loading shared libraries: libpython3.9.so.1.0: cannot open shared object file: No such file or directory

Now some info:

PYO3_PRINT_CONFIG=1 cargo build

Output:

PYO3_PRINT_CONFIG=1 cargo build
   Compiling pyo3-ffi v0.17.3
error: failed to run custom build command for `pyo3-ffi v0.17.3`

Caused by:

Reproduce the pyenv and cargo run commands on the reported Pop!_OS/Ubuntu setup, then inspect the pyo3-ffi build output produced by PYO3_PRINT_CONFIG=1. Compare the reported lib_dir and lib_name with the runtime loader failure; done means identifying whether PyO3 needs a repository-level fix or the issue is environment-specific.
