guile.info normally doesn’t need to be built when using the tarball.
However, this wasn’t the case until a9ea4f909b9970c755b0a7c4cd9da907e66496fc.

(Where 2 is ENOENT.)

Quoting http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13958#8 :

  [T]here are only two occurrences of EAI_SYSTEM in inet/getaddrinfo.c
  in glibc: one is for NETDB_INTERNAL, and the other is for
  IDNA_DLOPEN_ERROR.

Most likely, that means that one of the NSS modules specified in
/etc/nsswitch.conf could not be loaded.

Could you strace the C program above and check what happens?

TIA,
Ludo’.
