NPF: boot time dlopen error

["g.lister" <g.lister%nodeunit.com@localhost>]

Hi guys,

I am running 6.1.4 stable on an i386 I have loaded the modules required
via boot.cfg:

        # modstat | grep npf
        npf               driver     boot       2     34883    -
        npf_ext_log       misc       boot       0     1091     npf,
        npf_ext_normalise misc       boot       0     929      npf,

During boot I get this message:

        Enabling NPF.
        npfctl: dlopen: Cannot open "/usr/lib/npf/ext_log.so"

The so exists in link form and is readable:

# ll /usr/lib/npf/

My npf.conf in regards to logging is a copy of the examples:

        procedure "log" {
                log: npflog0
        }

My ifconfig:

        # ifconfig npflog0
        npflog0: flags=0

So I am at a loss as to why it is not getting loaded?? What am I missing?
Thanks in advance.
George
