MacPorts would prevent you from uninstalling a port that is needed (as a
library or runtime dependency) by another port.
If MacPorts allowed you to uninstall a port but rev-upgrade then reported
something broken, that would be a bug in a port. (A port has forgotten to
declare a dependency on the port(s) you uninstalled and has opportunistically
used it. Please file a bug report for each such situation you find so that it
can be corrected.)
