The ‘PATH’ environment variable is empty.  So this should be:

  (let ((tar (string-append (assoc-ref %build-inputs "tar")
             "/bin/tar")))
    (zero? (system* tar "xvf" tarball)))

And tar needs to be explicitly added as an input.

Note ‘zero?’ to make sure ‘tar’ exits normally.

See ‘package-from-tarball’ for an example, in bootstrap.scm.

HTH,
