No reply in a number of hours, so here is a suggestion from ignorance :-}

?Startup refers to a number of other "site and user files to process for 
setting environment variables" but not to Rcmd_environ. The contents of 
$R_HOME/etc/Rcmd_environ seem to reflect (some of) the contents of 
(some) other files.

I have similar lines (defining library paths) in

Is it correct to directly edit Rcmd_environ or should it be modified 
only via other files? (A genuine question).
