You're right. I don't currently see anything in Posit's instruction
that could have caused this.

Congratulations on getting R running!

I'm afraid that's not the way R is intended to be working. I think
there's something else currently broken in your R installation, though
feel free to ignore me if you don't want to deal with this right now.

There should be no need to create such symlinks when installing R: if
told to run from under a given prefix, it should be entirely possible
to avoid touching the rest of the filesystem. Are you sure you didn't
have R_HOME or some other environment variables interfering with the
workings of R? Was the R-4.1.3 installation also built from source the
same way you were building R-4.2.2, or did it come from an RPM?
