Problem with namespace installing rJava

I am installing rJava on a 64bit machine, running Windows XP, and am encountering the weirdest message. Below is the log. Has anyone seen this before? Thanks in advance.

 > install.packages("rJava")

  LoadLibrary failure:  The specified module could not be found.


Error: package/namespace load failed for 'rJava' 

Looks like a garden-variety binary incompatibility to me.

The NAMESPACE is a red herring as it happens to load the dynamic library, and that's where the trouble lies.

Does the DLL file exist at that path? If it does, than maybe it's one of its dependencies that's missing. Try http://www.dependencywalker.com/ to identify which one.

After that...?
