I don't find that explanation satisfactory. (The one about upgrade vs downgrades.) -u expands to --update means to install the *best available version*, not the *highest version number available*. If an ebuild goes from x86 to being hardmasked, --update should downgrade. If an ebuild of insanely high version number gets removed, --update should downgrade. I can explain why emerge openoffice and emerge --deep openoffice are different. emerge --deep openoffice basically does something similar to emerge --oneshot <everything openoffice has in its dependency>. So every package in the dependency tree will be considered, and if not at the *best* version it will be updated. Compare to emerge openoffice where only if a change of ebuild in openoffice changes the dependency will trigger installation of new or updated versions of dependencies. (Basically, you already have a version of whatever perl class it wants, and the ebuild specifies >= some really low version, so the dependency is satisfied and won't be considered in the emerge.) What I can't explain is why emerge --update --deep world misses the update! dev-perl/Archive-Zip is (correct me if I am wrong: I didn't see it mentioned in the changelogs so I assume it was not changed) in the dependency tree of both the Nov 3 and the January versions of openoffice. So --deep should traverse down there and find that one of its dependencies requires an update. At least that's what I expect based on "man emerge". Best, W -- Willie W.
