Did you actually mean that, Dirk? I would expect that R_HOME would be set by "myR CMD whatever" before it got to the configure script, so that the default R would only be used as a last resort. And R rather actively defends itself against R_HOME being set in its environment.

E.g.

$ R_HOME=/tmp R CMD env | grep R_HOME
WARNING: ignoring environment value of R_HOME
R_HOME=/Library/Frameworks/R.framework/Resources

(I'm not sure that it is actually supposed to work, but apparently R CMD foo executes 'foo' in the same environment as R CMD check et al.)
