I'm installing a new gentoo x86-64 linux system. After emerging system, and continue to emerge rp-pppoe, it happened. It looks like there's some headers conflicting with rp-pppoe-3.8-r2. As I downgrade linux-headers-2.6.23-r3, it passed emerging rp-pppoe.

See if re-emerging glibc after you update linux-headers fixes your problem. In any case, this is not net-dialup's problem. Reassigned to toolchain team.

Same problem over here
I have this problem too. But according to the error message: /usr/include/linux/in.h:26: error: redeclaration of enumerator 'IPPROTO_IP' /usr/include/gentoo-multilib/amd64/netinet/in.h:34: error: previous definition of 'IPPROTO_IP' was here The error indicates some symbols are redeclared in two files -- /usr/include/linux/in.h and /usr/include/gentoo-multilib/amd64/netinet/in.h. The former belongs to linux-headers and the latter belongs to glibc So I ran these two commands in order to compile rp-pppoe. 1. mv /usr/include/gentoo-multilib/amd64/netinet/in.h /usr/include/gentoo-multilib/amd64/netinet/in.h.bak 2. touch /usr/include/gentoo-multilib/amd64/netinet/in.h Then rp-pppoe is merged successfully on my mechine. Of course, don't forget to restore /usr/include/gentoo-multilib/amd64/netinet/in.h Have a try :)

Of course, movin' in.h has helped me, but I think that isn't good idea...

This is a workaround, not a solution. The solution would be either removing the definition from one of the header file that defines it, either the one installed by glibc or the one installed by linux-headers.
