Hi Peter,

Looks like there's a bad interaction between click-fastclassifier and 
click-devirtualize.  I'll look into this today.  The warnings are not important, 
FYI; the problem is this:

/tmp/clicktmp261/_devirtualize.ko: unresolved symbol __vt_20FastClassifier_a_ac0
click-install: '/sbin/insmod /tmp/clicktmp261/_devirtualize.ko' failed
