You need the *binary* package for windows. If you're lucky, all you  
have to do is to install the package on your Mac and zip it up (the  
*installed* package, not the source!).

So for example
mkdir /tmp/pkg
R CMD INSTALL -l /tmp/pkg ChemoSpec
cd /tmp/pkg
zip -r ChemoSpec_1.0.zip ChemoSpec

If you get unlucky, you have to use a Windows machine (or more  
conveniently Windows in a VirtualBox ;)) to build the binary package.  
(There are ways to cross-compile, but if you have no native code you  
should not need to go there ...).

Cheers,
