It does not appear so.Is that not included in the kdeutils package?
What's a little weird is that kdeartwork contains icons for it: /usr/share/icons/Locolor/16x16/apps/kpackage.png /usr/share/icons/Locolor/32x32/apps/kpackage.png /usr/share/icons/kdeclassic/16x16/apps/kpackage.png /usr/share/icons/kdeclassic/32x32/apps/kpackage.png /usr/share/icons/kdeclassic/48x48/apps/kpackage.png
And the localization packages contain data for it: /usr/share/doc/HTML/da/kpackage /usr/share/doc/HTML/da/kpackage/common /usr/share/doc/HTML/da/kpackage/index.cache.bz2 /usr/share/doc/HTML/da/kpackage/index.docbook /usr/share/locale/da/LC_MESSAGES/kpackage.mo
...yet it indeed doesn't appear to be in any of the core rpms.
I've never used it, but from the poster's description it sounds like a nice package-management tool for the individual user.
