This looks like a bug to me but I'd like to ask for further advice before reporting it as such, I might have overlooked something. Thanks for any help.
I'd suggest you should contact the package maintainer. It's not hard to find a copy of the cat utility function (e.g. in the Rtools used for building R and packages), but the error does suggest the package may not be intended to be used on Windows.
