That sounds typical.  You can use ccache and tmpfs to speed it up a 
little bit, but both rust and llvm are computationally massive.

Even worse, poudriere doesn't need to build it.  If you aren't changing 
its options there's no functional difference between building it locally 
and installing from the public pkg repo.  Poudriere does have the 
ability to install from pkgs, but there is a 2-year-old bug that 
prevents that feature from working correctly.

I recommend everyone comment on issue #822 on the freebsd/poudriere 
github[1] and explain how much of a pain it is that poudriere doesn't 
have sane behaviour wrt dependencies.  Maybe if enough people comment it 
will spur a fix.
