Pushed a new commit, hopefully it's fixed.

but it builds successfully from master. Maybe you need to rebase?

[TomaSajt]

Yup, I think I also figured it out.
Probably a result of rstudio/rstudio#16336

[b-rodrigues]

Working on aarch64-darwin!

[Kupac]

Builds and works on x86_64-linux. Both rstudio and rstudioServer. LGTM!
