Thanks for the suggestion, Gavin,  But well, let me count the ways ....

i)   As a general principle, I prefer to minimize env variables. So on Linux,
     I prefer (and use) ~/.Rprofile and/or ~/.Renviron, or even the site-wide
     ones

ii)  Similarly, I asked for site-wide config as that can be scripted.
     Your solution, if it worked, would not (as easily) allow that.

iii) The question was specific about the intentional castration of R CMD ...
     I actually get the .libPaths() adjusted on Windows too via the method
     mentioned in i)

iv)  When I do what you helpfully suggest, .libPaths() in R shows the entry
     twice yet the braindead R CMD check .... __still fails the same way__ not
     being able to load the very package tested from the location that is __not
     below__ the $R_HOME/library/ path.

This really is silly beyond words, but seemingly all by design and intentional.

Dirk
