[R] Creating packages in 1.8

[Seth Falcon]

Does R CMD check succeed if you unset R_HOME (or unset R_ENVIRON?).

The R shell wrapper script writes the warning message to STDOUT if
R_HOME is set to something other the setting hard-coded into the
wrapper.

This can be a problem if other scripts are depending upon the output of
R CMD <BLAH> stuff.  For example, I could not build RPy until I unset
R_HOME b/c RPy's build script relies upon the output of R CMD HOME and
it didn't like "WARNING: ..." as an include path ;-)
