unable to install webr

[amandasaksida]

Hi,
I wanted to produce pies using Pie.Donut function as suggested in the Pie Chart Revisited manual, but am unable to load webr (R 3.5.3, Mac OS X 10.14.1), getting the error message related to loading libraries, copied below.
the StackOverflow topic https://stackoverflow.com/questions/50398836/rstudio-wont-allow-me-to-install-the-package-imager suggests this is the dependency issue of the package on a not-explicitly R piece of sofware (X11).
Do you maybe know the way around this?

Error in dyn.load(file, DLLpath = DLLpath, ...) :

Hi,
Same error here.

_ERROR: lazy loading failed for package ‘webr’

Is there anyone checking on this?
thank you!
