The  %define __find_requires %{nil}  sounds too disruptive. I'll look at
scripting the corrections.

Maybe I will request at EPEL to see they would consider making a link to
/usr/bin/r. However I checked a Debian installation, and it's not there
either. So I don't know what the creators of the CRAN package are targeting.

Thanks again
