Looks like the default install perf install for config.vm.box = "bento/ubuntu-20.04" has the libunwind support.

Installed with

sudo apt update 
sudo apt install linux-tools-common
sudo apt install linux-tools-5.4.0-29-generic

[jfischoff]

I have no idea why this is necessary but I need to modify the ghc settings

vim ~/.stack/programs/x86_64-linux/ghc-tinfo6-8.8.3/lib/ghc-8.8.3/settings

to

 ("C compiler link flags", ""),

Need to add

ghc-options:
  "$everything": -g2 -O2
