Activating both options IPSEC and SCTP in kernel fails

Hello all,

I want to enable both IPSEC and SCTP on my FreeBSD 6.2
machines. I
applied the newest kernel patch from sctp.org (of september
2007) and
activated options SCTP. This works well, SCTP works well.
It is also possible to activate options IPSEC and compile a
kernel but
unfortunately _not_ in combination with options SCTP.
Those are the errors occurring when trying to make
buildkernel with both
options activated:

(The whole log of make buildkernel can be found at
http://ol
iver-roll.com/make_buildkernel.log (~800 KB), only the
error
messages at http://oliver-roll.
com/errors.txt and my kernel
configuration file at http://oliver-roll.co
m/SCTP.txt).

I think there is a conflict between
/usr/src/sys/netpisec/keydb.h and
/usr/src/sys/keydb.h which are both included somewhere in
the code.
Can anybody give me a hint about how to solve this
conflict?

Thanks & regards,

Oliver
