Not necessarily, I think. The easiest way to clamp to the current version would be to make a "shadow port dir that overrides the default one. Besides, what's wrong with "this port has a newer version but it's 'held' so we simply skip the upgrade and hope the user knows what he is doing"? I think we an rely on the version checking already implemented in the configure/cmake code, and possibly try a bit harder (where necessary) to present the actual error message to the user rather than "go check the log file".
