Installing Emacs 28.1 on a shared aging OS

I want to use Emacs 28.1 on aging OS that I mustn't modify /usr. I tried Docker but I want to use local command too. SBCL didn't work properly on old Docker. So I install Emacs from a source tarball to my home directory.

However, Emacs failed to verify TLS certs. So I installed GNUTLS, Nettle, Idn, and Unistring.

#!/bin/bash

export PKG_CONFIG_PATH=$HOME/lib64/pkgconfig:$HOME/lib/pkgconfig
export LD_RUN_PATH=$HOME/lib:$HOME/lib64
export LD_LIBRARY_PATH=$HOME/lib:$HOME/lib64
export LDFLAGS="-L$HOME/lib -L$HOME/lib64"
