About 85. But it's worse than that, as libxml2.dll itself imports from zlib1.dll and iconv.dll, and there is one of the latter in the application directory in R >= 2.6.0. So even if you find the right libxml2.dll, you may not find the right zlib1.dll and iconv.dll (and I already knew that you found R's iconv.dll, which fortunately works). I think we do need to provide an interface to SetDllDirectory, probably as an additional argument to dyn.load. -- Brian D.
