If you use port -Rn upgrade all depending ports will be rebuild. Are you 
sure git-core builds against a specific version and does not work with 
the new one? Usually there is no need to rebuild dependents.

I think you ran into this message which makes you think it depends on 
the old version. Dependencies are (not yet) version aware, so you need 
to use port -f uninstall to remove a port which has dependents - even if 
another version is still active. Uninstalling inactive versions is 
always safe.

Gentoo already has a project for portage in a prefix on alternative systems.
