I have ufo2000 emerged, it depends on dump. When I do "emerge -Duvp world" portage wan't to downgrade it, after that upgrade, after that downgrade...

After you've upgraded it, do echo "<media-libs/dumb-0.9.3-r1" >> /etc/portage/package.mask and find out what depends on it.
It is ufo2000 itself: !!! All ebuilds that could satisfy "~media-libs/dumb-0.9.2" have been masked. !!! One of the following masked packages is required to complete your request: - media-libs/dumb-0.9.2-r3 (masked by: package.mask) - media-libs/dumb-0.9.2-r2 (masked by: package.mask) For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook. (dependency required by "games-strategy/ufo2000-0.7.1062" [ebuild]) !!! Problem resolving dependencies for games-strategy/ufo2000 !!! Depgraph creation failed.
See Bug 134267, it won't work with dumb >0.9.2
