For me, the problem was that I needed to have zlib (and possibly openssl@.1.1 and readline) installed from homebrew, and then having the following environment variable set.
I'm having this same issue after re-installing pyenv (no issues prior to re-installing, but this is the first time I've needed to re-install after upgrading to Big Sur, so I think it's related). Trying your solution now.
Edit: Just reporting back — this worked for me. Thank you very much.
Others who come across this might also want to install and link bzip2 prior to compiling.
This is a snippet I use on all my machines, if you don't always use brew you could always wrap it in an outer check. And yes the -O2 might not be for everybody, then just skip it :)
This one will adhere to whatever location you might have used for Linux Homebrew, on Darwin you would always use /usr/local, since otherwise a lot of brew stuff fails, and it would be a pointless pain to workaround.

For me, the problem was that I needed to have

Hopefully this helps!
Thank you, this worked!
