When running ruby-install, it fails to build. This also reported in rbenv issues (https://github.com/rbenv/ruby-build/issues/1725).
for example when installing ruby 2.6.8
# installing via ruby-install ( https://github.com/postmodern/ruby-install )
ruby-install ruby 2.6.8
it results in the following error
ossl_x509store.c:452:30: note: ')' token is here
result = rb_funcall(ctx, rb_intern("verify"), 0);

seems to be complier issue. first ensure that xcode is installed appropriately. In my case, I had it installed prior but you can opt to reinstall to be sure. hope this helps people save time trying to figure out the issue as compiling it takes several minutes.
# check xcode, should yield : /Library/Developer/CommandLineTools
xcode-select -p
# check xcode, should yield : xcode-select version 2384
xcode-select -v
# install xcode-select
xcode-select --install
# reinstall openssl and version 3
brew reinstall openssl@1.1
# install build dependancies
brew install openssl readline libyaml zlib bison bison@2.7
# ensure build is using bison
export PATH="$(brew --prefix bison@2.7)/bin:$PATH"
# set ruby compilation flags
export CFLAGS="-Wno-error=implicit-function-declaration"
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.1) --with-readline-dir=$(brew --prefix readline) --with-libyaml-dir=$(brew --prefix libyaml) --with-zlib-dir=$(brew --prefix zlib)"
# install ruby via ruby-install
ruby-install ruby 2.6.8
I had the same issue when I ran the following command: ruby-install ruby 2.6.8 -- --with-openssl-dir=$(brew --prefix openssl@1.1).
I updated bison with brew install bison@2.7 and ran export PATH="$(brew --prefix bison@2.7)/bin:$PATH" to fix ripper. Then, re-running the initial ruby command worked!
I can not install any rubies by compiling on Big Sur. I get this:
