It seems that `http-get` do not manage SSL, and
GNU site 302 to https version (or is it just my proxy config?)

So here is example for other url:

        (use-modules ((web uri) #:select (string->uri))
                     ((web client) #:select (http-get)))
        (use-modules (rnrs io ports))

        (define *url*
          "http://hackage.haskell.org/package/HaTeX-2.1.3/HaTeX-2.1.3.tar.gz";)

        (call-with-values
            (lambda () (http-get (string->uri *url*)))
          (lambda (res-headers res-body)
            (with-output-to-file "some.tar.gz"
              (lambda () (put-bytevector (current-output-port) res-body))
              #:binary #t)))
