Thanks for taking the time to follow-up on this.

A few quick comments:

i)    There are several entries because I (at compile time) deconstruct the
      LD_LIBRARY_PATH set by /usr/bin/R (a shell script) used to load R from
      /usr/lib/R/bin/exec/, this uses /usr/lib/R/lib.  We could strip every
      thing but /usr/lib64/R/lib and the Java libs, but why bother

ii)   /usr/lib/R/lib (or /usr/lib64/R/lib) is needed and will not move,
      unless someone (you ?) convinces R Core to change it. (Hint: Won't
      happen).   This is how it is, this has been discussed before and you
      are kindly invited to read up on the old discussions.

iii)  /usr/bin/r, for which I am 1/2 of upstream, won't change either because
      this embedding of R is its whole point (vis-a-vis the shellscript /usr/bin/R)

My post was a false alert anyway; I had one actual bug with an 'empty' entry
and that has been fixed. 

Cheers, Dirk
