Comment (by iEFdev):

 Replying to [comment:13 kencu]:
 > I have to figure out which versions of `llvm` support this configure
 flag to turn the `go` bindings off. Unfortunately not all of them, no
 doubt, so there will be some inconsistency in the `llvm` ports wherever
 this break comes.

 You can add llvm9 to the list.

 And it (re)installed everything with `+universal` tonight when I upgraded.
 Was that supposed to happen? It's never done that before.

 I got `clang_select`+ a few others, and the it wanted to reinstall som
 10+15 programs - and all had the universal variant selected. Now, since
 the install break, I reverted them back… (uninstalling + activating the
 one I hade before). I thought I had `-universal` in variants.conf, but
 appearently I didn't. I'll try to reinstall everything now with the
 `-DLLVM_ENABLE_BINDINGS=OFF` added.

 // Adding the log incase you want/need that one
