My workstation has been stuck in a quasi-working state for a long time now (a month?). Basically I updated to Python 2.5, then tried to update to Eric4 since Eric3's dependencies wouldn't build on Python 2.5. The Eric4 thing never worked, so I removed it. A little later when KDE 3.5.5 was marked stable on AMD64 I wanted to upgrade to keep the machine up to date, but every attempt to build KDE would result in complaints about the Qt version.
