I suspect this is the root cause and that the "wrong" global variable is be=
ing=20
used in ipsec_output.c due to duplicate symbols.

OTOH, have you created an enc0 device?  I can't find anything that=20
automatically creates it.

Just one point: you do not need DEV_ENC.  If you have 'device foo', config(=
8)=20
automatically enables a corresponding DEV_FOO option if it is listed in=20
sys/conf/options*.
