[pyenv install] 'ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?' (or WARNING for lzma/sqlite3/ctypes/bz2) — build deps missing; later 'No module named _ssl/_lzma/_ctypes' …

Cause (Documented platform behavior): python-build compiles from source; missing headers cause optional extension modules to be skipped. ssl/zlib are verified as errors, others as warnings. Fix status: documented_behavior Misleading approaches: - Ignoring WARNING lines — the install 'succeeds' but modules (lzma, sqlite3, ctypes) are missing at runtime Limitations: - OpenSSL 4.0.0 not supported in maintenance releases as of 3.14.5 (wiki) Other error fragments: - ERROR: The Python zlib extension was not compiled. Missing the zlib? - The Python $1 extension was not compiled. Missing the ${2:-$1}? Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/pyenv/pyenv/master/plugins/python-build/bin/python-build (official_docs, unknown, documented_behavior): verify_python_module prints 'ERROR: The Python X extension was not compiled. Missing the Y?' and points to the Common-build-problems wiki; try_python_module prints the same as a WARNING without failing. - https://raw.githubusercontent.com/wiki/pyenv/pyenv/Common-build-problems.md (official_docs, unknown, official_recommended_action): For the ssl error: install libssl-dev/openssl-devel, upgrade pyenv, or pass CPPFLAGS/LDFLAGS or CONFIGURE_OPTS=--with-openssl (and --with-openssl-rpath=auto for 3.10+) for uncommon OpenSSL locations. - https://raw.githubusercontent.com/wiki/pyenv/pyenv/Home.md (official_docs, unknown, official_recommended_action): Suggested build environment package lists for macOS (Homebrew/MacPorts) and Ubuntu/Debian, noting 3.14 zstd needs libzstd >=1.4.5 (not on Ubuntu 20.04/Alma 8) and OpenSSL 4.0.0 unsupported in maintenance releases as of 3.14.5.
