rsync 2.5.5 and aix 4.3.3

[Alvaro Gomes Sobral Barcellos]

Hi, (AGAIN...)
    At Rs6000/AIX-4.3.3 the rsync-2.5.5 
(compiled with --disable-ipv6 and --disable-debug) works ok 
when make local connections or I use -e rsh or -e ssh 
for remote connections, like:

(OK) ./rsync -vacz  . /user
(OK) ./rsync -vacz -e rsh . user at 10.4.2.199:user
(OK) ./rsync -vacz -e ssh . user at 10.4.2.199:user

but with standart remote rsync without -e

(NOK) ./rsync -vacz . user at 10.4.2.199::user

returns:

rsync: failed to connect to 10.4.2.199: Addr family not supported by
protocol
rsync error: error in socket IO (code 10) at
clientserver.c(97) 

I need users can sync files without have "real" users at box.

any tips?
