[R] R.oo in R-3.0.1

[Henrik Bengtsson]

Hi, R.oo author here:

This looks like a possible namespace issues, which might have gone
under the radar if you have only used R v2.11.x until now.  Could you
forward me your MyPackage test package so I can troubleshoot/reproduce
(I think the answer is in your DESCRIPTION/NAMESPACE file).
