How did you try to install it?  It is not a Windows binary package, but a 
Linux binary package.

Because you need more than R to install source packages on any platform. 
See the R-admin manual.

Well, it _is_ a suggested method: see README.packages.

Another method open to you is to cross-build on Linux, also described in 
that document and in R-admin.html.  You would need to do that is there is 
anything Windows-specific about the package.

Note that none of these methods produce Windows-specific forms of help 
(and one of those is the default). The only way to do that is under 
Windows (including using Windows tools under emulations such as Wine on 
other OSes).
