Issues setting up a Rumprun toolchain in macOS

[beriberikix]

Has anyone tried setting up the rumprun toolchain on the latest macOS High Sierra? I've had issues tried to manually build the toolchain, only to get cryptic errors when I run build-rr.sh.

I also tried the docker route, but it didn't include qemu, so rumprun qemu failed. Also, I failed to install via apt-get and building from src felt like yak shaving.

Anyone get it working? I tried IRC but didn't get a response.

Thanks!
