[Openswan Users] Error compiling 2.5.17 (KLIPS, vanilla kernel)

[Muenz, Michael]

Hi,

today I plan to upgrade my VPN-Server from 2.4.11 (KLIPS, NAT-T)
to 2.5.17. It's a Debian Etch with a 2.6.23.14 vanilla kernel.

"make programs" does it's job very well, but when executing
"make module" I get:

ln -s -f /root/source/openswan-2.5.17/linux/net/ipsec/ipsec_tunnel.c 
/root/source/openswan-2.5.17/modobj26/ipsec_tunnel.c

Can't find anything suitable with google. Any ideas?

Thanks
