Gemspecs don't work like this. They get interpreted and turned into JSON so this only really parses the deps based on the system where the gemspec is uploaded

Indeed, these have to go into the Gemfile.

OK I was running out the door when I wrote that as was being very dumb.

Gemfile of course also will not work.

After much discussion with @Stromweld I think the only way to continue to support old versions of ruby that Mac's still have, is to branch this per ruby era, and have different major-versions of mixlib-install per ruby era.

This will get simpler as Mac is the only real reason we have to support ancient Rubies, and they're going to be dropping Ruby altogether, and then as older versions of Mac get EOLd, which happens pretty frequently, we can stop caring.

So I'm thinking something like:

• keep 3.x as ruby < 2.7
• branch a 4.x for ruby >=2.7, < 3.3
• branch a 5.x for ruby >=3.3, < 3.4
• branch a 6.x for ruby >=3.4, < 4.0
• main becomes 7.x for 4.0+

So Order of operations here is something like:

• adapt Ci to move all stuff to GHA instead of BK
• branch and lock versions
• fix openssl on each branch
