Dear Henrik, Thanks for getting back to me. Apologies - have resolved the problem myself. The package in question has quite a bit of legacy code written by others and as it appeared had explicit library() calls inside the source code on the top level. After removing those calls things started working. In fact I have realized this by creating a small package containing just this code in question and seeing this work just fine, so that prompted me to look further into other source files in the original package etc.
There is no issue to look into at this point as the package works just fine. Thanks again.

Could you forward me your MyPackage test package so I can troubleshoot/reproduce (I think the answer is in your DESCRIPTION/NAMESPACE file). /Henrik On Wed, Aug 21, 2013 at 2:47 PM, Grach, Alexander <alexander.gr...@credit-suisse.com> wrote: > Fellow R users, > > I'm trying to upgrade from 2.11 to 3.0.1.
