My answer to https://community.rstudio.com/t/install-arrow-from-posit-package-manager-binary-in-ubuntu/170776/2 which is waiting for moderation.

You need some system packages as well that arrow.so is linking to. There are different ways to see what exactly.

1. You can manually inspect arrow.so using ldd arrow.so so see what is missing.

2. Some packages, e.g. pak can look up system requirements. The devel version (from https://pak.r-lib.org/reference/install.html#nightly-builds) is better at this:
