(usagi-users 03791) ping doesn't work as normal user?

Hi,

I git pulled iputils from USAGI git tree but ping doesn't seem to work as 
normal user :

[~/GIT/USAGI/iputils]> ./ping www.google.com
ping: icmp open socket: Operation not permitted

strace shows:

[...]
fstat64(3, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 1), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 
0xb7fd8000
_llseek(3, 0, 0xbffcdd70, SEEK_CUR)     = -1 ESPIPE (Illegal seek)
write(3, "ping: icmp open socket: Operatio"..., 48ping: icmp open socket: 
Operation not permitted

it works fine as root :

[~/GIT/USAGI/iputils]> sudo ./ping www.linux-ipv6.org
PING moon.linux-ipv6.org (203.178.141.227) 56(84) bytes of data.
64 bytes from pc14.fujisawa.wide.ad.jp (203.178.141.227): icmp_seq=1 ttl=42 
time=411 ms


Any idea what might be wrong?
