rsync - Aug 2002 - rsync 2.5.5 and AIX-4.3.3

Hello,
	I made a collection of GNUs to RS6k AIX-4.3.3, but rsync refuses to
work between hosts, i get:
 
rsync: failed to connect to X.X.X.X: Addr family not supported by
protocol
rsync error: error in socket IO (code 10) at clientserver.c(97)

Details:  
libc.a (original), gcc 3.1.1, binutils 2.13, make 3.79.1,

/etc/services: 
rsync           873/tcp                         # RSync
rsync           873/udp                         # RSync   

compiled with:
./configure --prefix=/usr/local --disable-ipv6

	Any Tips ???
