iptraf compile error

[yoda]

I'm trying to compile iptraf and I get the following error....


/usr/include/net/if.h:45: error: parse error before numeric constant
/usr/include/net/if.h:111: error: redefinition of `struct ifmap'
/usr/include/net/if.h:126: error: redefinition of `struct ifreq'
/usr/include/net/if.h:176: error: redefinition of `struct ifconf'
make: *** [iptraf.o] Error 1

I'm running LFS 6.1 with kernel 2.6.16.11

Any ideas?

thanks
