I think it's a bug, or 'some unnecessary fragility' in the build system.
A user noticed the same in one of the beta/rc pre-releases I made of R 2.7.0
for the Debian distro. I immediately reported this to Prof Ripley, but I
never received a reply.
A few easy-ish ways to fix it are:
i) Define the environment variable RHOME and point to /usr/local/r-2.7.0;
if the variable exists Rscript will ignore the compile-time setting.
ii) Similarly, just alter the code and override rhome in line 67:
static char rhome = R_HOME;
iii) Correct the fragility in the build system by something like
$ cd src/unix; R_HOME="/usr/local/r-2.7.0" make Rscript
which should work.
iv) Just switch to littler :-)
