Yes. I have found that there is a requirement to utilize libcholmod with 
    libcamd and probably with libmetis. See, for instance, 
http://www.cise.ufl.edu/research/sparse/cholmod/. It is written there 
that cholmod optionally requires camd, but it seems that -lcholmod must 
be put with -lmetis as well.

Although I'm not sure I go right a way I do modify configure file 
(Octave-2.9.9) in a manner of:

It works for me.
