well, the workaround shows that the breakage is on a fairly shallow level. 
However, the broader theme is that there is simply no guarantee that the CRAN 
Mac binary packages are compiled in a way that is compatible with our 
Macports-based installation of R. They may work, now, but I guess the problem 
is fairly likely to come back to bite us - possibly in much more subtle ways.

As inelegant as that is going to be, I think it might be a better idea to use 
the official CRAN Mac binary version of R for the bundle. Not sure how this 
could be made to work. Perhaps roughly like this:

- First build as usual using Macports
- From update_bundle.sh, wipe the R port, install CRAN R binary, in its place.
- Rebuild RKWard only, to make sure it is linked to the CRAN R binary, 
appropriately
- Package everything

Well, my idea of how the bundling works is still rather limited. Does this 
seem entirely impossible?

(Normal macports-based source installation would continue to work the way it 
does, although probably, there, I should revert the default to installing R 
packages from source, not binary?).

Regards
Thomas
