Could you apply this patch:

diff --git a/guix/ftp-client.scm b/guix/ftp-client.scm
index f02d460..e76f08a 100644
--- a/guix/ftp-client.scm

   (let loop ((addresses addresses))
     (let* ((ai (car addresses))
-           (s  (socket (addrinfo:fam ai) SOCK_STREAM ;TCP only
-                       (addrinfo:protocol ai))))
+           (s  (socket (addrinfo:fam ai)
+                       ;; TCP/IP only
+                       SOCK_STREAM IPPROTO_IP)))
 
       (catch 'system-error
         (lambda ()

and then try again, with:

  ./pre-inst-env guix package -i autoconf

(I can provided more info on how to apply the patch if needed.  See also
<http://www.gnu.org/software/guix/manual/html_node/Running-Guix-Before-It-Is-Installed.html>.)

This may be a regression introduced in 279ec1d.

TIA!
