Building snort

Hi all, I am building a high speed IDS system trying to use pfring extensions, with libpcap modified. I'm trying to work with unified output format. Kernel is built ok. New libpcap seems ok too. When I build snort (downloaded 2.7 and 2.8.1), I try to make it static building against the libpcap.a just generated. All I can see is that the resulting binnary does not give any dependence (ldd) against any libpcap. So I launch it... But the unified file format it generates is wrong because it´s full of messages of this kind: "[**] [116:6:1] (snort_decoder) WARNING: IP dgm len > IP Hdr len! [**]" Even if we have the option to avoid these messages in snort.conf. I guess I get a message for each packet we receive... The logs get enormous (50 Mbps link) and without any value. Any hint?? Any other data I should supply? On the other side, I have an old snort binnary linked to the modified libpcap (that's what ldd says...) that seems to work ok (loads pfring on startup and gives normal alerts), but I compiled it before we had the pfring change (kernel and new libpcaps)??? It shouldn't work this way. Building snort is being a strange experience for me, because I get to many issues I can not fully understand... The flags I try to pass to configure script never seem to do anything... I'm turning crazy.
