Upgrade CentOS linux ports stack to 6.7
In general it looks ok. I haven't validated the plists or such. The Mk files look good (no obvious error). The rest seem to be "a simple version update".
Required before commit IMO: exp port build run, it detected some issues a normal build by hand didn't show (when I worked on the 64bit parts).
- Add plist variables for version numbers used in the plist. This is not a showstopper, just an impormvent suggestion to ease future updates.
- pull updates from CENTOS_LINUX_UPDATES site:
