Metis 4 has license and availability issues so move to metis5 which produces the same tests results as previous versions.
Use the BSD/darwin memory detection instead of just reporting an error.
Pet portlint while here.

patch with fix for memory handling
Add dependency on calculix-ccx which will stop using taucs to avoid having the secondary metis4 dependency right away (I have to do a lot more testing with the new metis before we can use it there).
