Portupgrade deletes the old version of the port by default. The PNG upgrade was a major PITA, because I installed one new port that thought it had to have it. I'm sure 98% of the ports I then had to upgrade would have still worked just fine even if rebuilt against the old libpng. I think the complaint here is that the port dependencies system frequently gives the impression/enforces the rule that new ports will depend on whatever the most current version of everything is in the ports tree at the time they were built, forcing sort of a perpetual upgrade cycle. IMHO this is probably due to naive port maintainers (such as myself) incorrectly pointing a port at libpng.5 instead of any libpng, or libpng >=3D 5. Once the ports tree is 'poisoned' in this fashion, there's really no going back. I'd sure vote for an audit of this behavior as a summer of code project. Long story short, anything that sounds fundamental gets bumped (png, jpeg, tcl, python, gtk, etc, etc), I just sit back and get ready to spend two or three days retrying portupgrade -akOf -mBATCH=3Dyes until everything sticks. If you've got OO or KDE4 installed, you might just want to forget it and pkg_delete -f *, then start over. I'm sticking by bsd though. You don't even have the opportunity to run an automated tool to clean & build everything from source automatically on linux. I'm sure rpm & apt dependencies are even nastier. Steve
