[Rd] Cross compiling with R250

[Prof Brian Ripley]

Have you actually tried this recently? If you don't set R_EXE you get
a fatal error:

---------- Making package base ------------
   adding build stamp to DESCRIPTION
/bin/sh: I failed to read the instructions to set R_EXE in MkRules: 
command not found

And MkRules says

# path (possibly full path) to same version of R on the host system
R_EXE='I failed to read the instructions to set R_EXE in MkRules'
