nice to hear from you! Indeed, I have been doing some housekeeping of the Pure packages, switching to the Open Build Service to make that easier. Doing SUSE and Fedora RPMs is next, the idea is that everyone should be able to find a suitable Linux package for the time being. But once that is done, the LLVM 8/9 port is the next thing on my TODO list (I stopped counting how many years I'm late with this).
Good luck with Rust! One of my sons uses it a lot these days, so I hear that it's very safe but also fairly inconvenient. Pure is exactly the opposite. :)
