The Windows code for package XML says
> XML:::.onLoad
function (libname, pkgname)
{
if (.Platform$OS.type == "windows") {
temp <- Sys.getenv("PATH")
Sys.setenv(PATH = paste(utils::normalizePath(file.path(libname,
pkgname, "libs")), temp, sep = ";"))
on.exit(Sys.setenv(PATH = temp))
}
library.dynam("XML", pkgname, libname)
if (exists("setMethod")) {
}
.C("RSXML_setErrorHandlers")
}
<environment: namespace:XML>
so it does already do that.
The order depends on the version of Windows *and* its settings: see
http://msdn2.microsoft.com/en-us/library/ms682586(VS.85).aspx
There is a way to change this:

but it would preclude Windows 2000.
Perhaps Martin can explain how libxml2.dll got into c:/WINDOWS/system32/?
My suggestion is that we rename the DLL when copied into library/XML/libs
to something like libRxml2.dll.
