On 10.6.8 Intel clang-3.4 is picked, and it also fails: ​https://build.macports.org/builders/ports-10.6_x86_64-builder/builds/173117/steps/install-port/logs/stdio

As you know, I have no access to such a system (nor do I have much motivation, tbh.) If you can find patches that fix this to be conditionally included on older hardware, we will of course accept them.

I will look into this. Intel systems are not a great priority for me to be honest, but for the sake of testing I would prefer this building, of course.

I'll also say directly that I don't care much about historical versions of MacOS. I care about current users of MacPorts. If people want to spend effort keeping old stuff going that's fine, but it's not something I want to spend time on. So, if you want to get it working, fine, and if not, fine.

No issues, I got your position. Why I assign a ticket is merely because you are the maintainer of OCaml and may still want to be informed. No obligation is implied whatsoever.
