Alex,

If you are not careful while modifying the config.mk file for the sparse
libraries, you can end up with a METIS dependency. In my case I installed
METIS, but you should be able to avoid that by carefully rereading and
reediting your config.mk in Ufconfig.

You do need CAMD installed, and what I do is export LIBS=-lcamd before I
./configure octave. The octave developers are aware of this issue, which is
apparently related to the version of the sparse libraries you are using.
