Thanks Duncan for the hints.
libxml2.dll is not in my c:/WINDOWS/system32, but in that of a user of
a package of mine. I guess installed by some other application, though
I don't really know what it's doing there (or the consequences of
removing it).
The MSDN site seemed in the long term to point in the direction of
side-by-side assemblies, which would require cooperation /
infrastructure from R.
