Have you tried gnuwin32.sf.net tar?

http://gnuwin32.sf.net/

Or you can try RubyInstaller DevKit and rename bsdtar to "tar"

Actually that tar is not used by the gem package but instead is
generated for support packages like .tar.gz or .tar.bz2

That is configured in the Rakefile of your project and can be turned
off with need_tar = false and need_zip = false

RubyGems will use it's own tar mechanism to package the gem and use
zlib to generate the gz compressed version of the contents.
