not quite sure why depscan.sh was ever added to portage, but there's no reason to run it ... depscan.sh regenerates init.d cache information and nothing else ... the init scripts themselves are hardy enough to determine whether the cache needs to be updated, so having portage run it after every frickin step is useless
Fixed on or before 2.0.51.22-r1
Looking through the batch of bugs, I'm not sure that some of these are actually fixed in stable. Others, the requirements have possibly changed after the initial fix was committed. If you think this bug has been closed incorrectly, please reopen or ask that it be reopened.
