I looked into suitesparse-metis and found the following: The CHOLMOD-Lib includes metis.h (in CHOLMOD/Partition/cholmod_metis.c), if NPARTITION is not defined. libparmetis-dev(3.1.1) includes metis.h along with parmetis.h (The newer version of parmetis in unstable didn't include any metis stuff anymore). But I really don't know, why suitesparse-metis depends on parmetis and not on metis. Thinking about that, removing suitsparse-metis seems to be the best options. Especially when you link the newest version of suitesparse against metis. A special metis-version of suitesparse wouldn't be needed then anymore.
