## Title

    Proposed fix: [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/_l

## Body

    Recommended action: Install the suggested build environment first (Ubuntu: make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev curl git libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev libzstd-dev; macOS: xcode-select --install and brew install openssl@3 readline sqlite3 xz tcl-tk@8 libb2 zstd zlib pkgconfig), then reinstall. For OpenSSL in unusual prefixes pass CONFIGURE_OPTS=--with-openssl=<prefix> (plus --with-openssl-rpath=auto for 3.10+).
    
    Option: Install the suggested build dependencies and rebuild [evidence: official_recommended_action]
    Applies when: Any pyenv install
    Steps:
    1. Install the distro package list from the pyenv wiki
    2. pyenv uninstall -f <ver> && pyenv install <ver>
    3. Check: python -c 'import ssl, lzma, sqlite3, ctypes, bz2'
    Expected: No WARNING/ERROR lines; modules import
