That's not the issue here.  Even if R_LIBS is set, R CMD check looks for 
the copies of the standard and recommended packages in .Library 
(specifically .check_Rd_xrefs does): that is a safety measure as those are 
the ones against which the checks should be done even if you have 
development versions elsewhere in R_LIBS.  (Not my design, but one that 
seems highly defensible.)

There is no provision in the R scripts to install the recommended 
packages elsewhere than .Library, but I believe Dirk has a post-install 
script that breaks the assumptions so this is a Debian-packaging-specific 
issue.

R CMD does not make use of ~/.Renviron nor R_HOME/etc/Renviron.site:
it is like R --vanilla, which is what is used for a lot of batch testing 
code.
