Problems with Squid

Hello gentoo alpha people,

I've noticed a problem starting up squid on my Miata box:

Jan 30 02:47:01 supper squid[6558]: Squid Parent: child process 6560 started
Jan 30 02:47:01 supper (squid): comm_select_init: epoll_create(): (78)
Function not implemented
Jan 30 02:47:01 supper squid[6558]: Squid Parent: child process 6560 exited
due to signal 6
Jan 30 02:47:04 supper squid[6558]: Squid Parent: child process 6676 started
Jan 30 02:47:04 supper (squid): comm_select_init: epoll_create(): (78)

due to signal 6
Jan 30 02:47:14 supper squid[6558]: Exiting due to repeated, frequent
failures

The system's up to date as far as I can tell:

net-proxy/squid-2.6.7
sys-libs/glibc-2.3.6-r4
sys-devel/gcc-3.4.6-r2
sys-kernel/linux-headers-2.6.11-r4

What am I missing?
