struct x*pcb size mismatch

I rebuild my system with HEAD sources as of today and began
experiencing the following problem:
[rionda_at_kaiser][~]> sockstat 
sockstat: struct xtcpcb size mismatch
sockstat: struct xinpcb size mismatch
sockstat: struct xunpcb size mismatch
sockstat: struct xunpcb size mismatch
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN
ADDRESS      
[rionda_at_kaiser][~]> 


Any idea of what can cause this problem?
Kernel and world are *not* out of sync: I recompiled both.

Thanks
Best regards
