The idea of temporary additions to the path during the
INSTALL/build/check code sounds reasonable. R could probably do it more
accurately than devtools or RStudio can (since we know the requirements,
and you have to guess at them), but could hopefully do it in a way that
isn't incompatible with those.
The code called by install.packages() and related functions within R is
essentially the same code as called by R CMD INSTALL etc from the
command line, so this would help both cases.
