1. What command did you run?

I ran ./configure --verbose --prefix=/Users/*****/.rvm/rubies/rbx-5.0 --with-opt-dir=/usr/local/opt/libyaml --with-opt-dir=/usr/local/opt/libksba --with-opt-dir=/usr/local/opt/readline --with-opt-dir=/usr/local/opt/zlib --with-opt-dir=/usr/local/opt/openssl@1.1

then make

2. What behavior did you expect?

I expected it to build correctly

3. What behavior did you get instead?

I think the make step failed because of llvm bindings to libxml2. On Mac and homebrew the @llvm_ldflags include an argument of -llibxml2.tbd which does not work. This comes from the llvm-config command on the line @llvm_ldflags = #{@llvm_configure} #{flags}.strip.gsub("\n", ' ')

4. What version of Rubinius?

5

5. What version of operating system?

Output of uname -a:

Darwin Kernel Version 19.5.0: Tue May 26 20:41:44 PDT 2020; root:xnu-6153.121.2~2/RELEASE_X86_64 x86_64

6. What is your operating system distribution, if your operating system has more than one?

My distribution is ...

7. How did you build your version of Rubinius?

• I used RVM.
• I used ruby-build.
• I used ruby-install.
• I built manually from a tarball.
• [x ] I built manually from a git clone.
• I installed a binary.

Note this behaviour is also apparent when attempting rvm install rbx-5

8. Does this issue involve proprietary code?

• Yes, this issue involves proprietary code that I cannot share.
• Yes, this issue involves proprietary code, but I am able to share it under certain conditions.
• [ x] No, this issue doesn't involve proprietary code.

9. Are you able to help us debug the issue?

• [x ] Yes, I'm able to help debug, including running commands under lldb.
• No, I'm not able help debug or I don't have time to help.

Note I manually modified this argument from -llibxml2.tbd to -lxml2. I don't know if it correctly built with that linked library but the make step passed. I don't know anything about llvm and I am adding it here just because it's probably an llvm Mac specific issue in case anyone is having the same problem.
