quote from the faq:
* Your kernel and userland are not synchronized (i.e., you built a
new kernel but did not do an installworld, or vice versa), and
thus the symbol table is different from what the user application
thinks it is. If this is the case, simply complete the upgrade
process (see /usr/src/UPDATING for the correct sequence).
recommended steps for updating the system are in the "cutting edge"
section of the handbook.
