Comment (by barracuda156):

 Replying to [comment:1 kencu]:
 > you cannot (easily) build libcxx with the current Portfile on 10.5 for
 PPC using gcc. I have done it, last time in 2018. It's a big project.
 > Anyway, mrustc uses LLVM to build it's code, but LLVM does not work on
 PPC Darwin, so lost cause until someone like Iain fixes llvm to work on
 PPC darwin (five years and counting :> ).

 Our friend @catap told me that Rust may allow using gcc soon. Probably
 sooner than `llvm` is fixed anyway )

 Have you retained your custom port file for `libcxx`? I won’t request you
 to waste time on explaining that step by step to me, but if I have your
 old WIP, I can probably make it.
