[Click] click Digest, Vol 94, Issue 3

Zi Feng,  Dongyu,

I could not replicate this problem.  Are you still having it?  It might be
that your compiler is not emitting the vtables for these generic interfaces,
which are defined only in header files.  I added some .cc files too to attempt
to fix the problem -- try "make elemlist; make" -- but I am not sure it will work.
