Aside from this issue, please set AUTOCLEAN in your make.conf to yes. It's a deprecated option, which caused all sorts of hard to resolve bugs in the past, if set to no.
What version of Qt is currently installed?
Currently installed qt version is 3.1.2-r4
Looks like that during the build uic is linking against your already installed Qt library vs. the one that's being built. I thought we had this one nixed, but I guess not. A workaround would be to unmerge your existing Qt verson first before merging this one, though that's definitely not the best solution.
Note that if unmerge Qt before merging a new version, your system will be left in a somewhat unusable (GUI) state, so do this at your own risk.
Unmerging and re-emerging qt seems to have solved the problem. Thanks for yourhelp.
Closing.
