--- Comment #6 from Eric <majzoube at umsl.edu> ---
Thank you for the instructions. My system is stock Fedora 38 with R version
4.3.1. The version of rkward shipped with F38 is 0.7.4 and it works fine.
Running rkward version 0.7.5 with --debug-level 5 shows an error in the output
of /tmp/rkward.rbackend:

...
... lots of stuff here that seems fine
