Bug#380652: squid fails to start because of "Function not implemented" error

Package: squid
Version: 2.6.1-3
Severity: grave
Justification: renders package unusable

On my kernel (2.4.28), starting the updated squid results in a crash
with the following logged in the syslog:

Jul 31 11:30:58 tea (squid): comm_select_init: epoll_create(): (38) Function not implemented

Running squid directly shows the following:

# su proxy -c '/usr/sbin/squid -N'
FATAL: comm_select_init: epoll_create(): (38) Function not implemented

Squid Cache (Version 2.6.STABLE1): Terminated abnormally.
CPU Usage: 0.130 seconds = 0.110 user + 0.020 sys
Maximum Resident Size: 0 KB
Page faults with physical i/o: 578

Running it directly and under strace shows the following:

# su proxy -c 'strace /usr/sbin/squid -N'
