We have a winner! (By bending the rules.)

That is less unconditional that I desired, but it works.

|         echo ${OLDWD} > ../inst/old.txt
|         echo ${PWD} > ../inst/current.txt
 
Then 'current.txt' is as before a temporary directory per R's build
conventions, but old.txt does indeed contain the source directory.

Close enought :)

Thanks very much for passing that creative hack along!
