> 				 (system* "tar" "xvf" tarball)

The =E2=80=98PATH=E2=80=99 environment variable is empty.  So this should b=
e:

  (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 =E2=80=98zero?=E2=80=99 to make sure =E2=80=98tar=E2=80=99 exits norma=
lly.

See =E2=80=98package-from-tarball=E2=80=99 for an example, in bootstrap.scm.

HTH,
