the binary "computeprof" is linked against libQtAssistantClient.so.4 which is provided by x11-libs/qt-assistant[compat] for (I think) all of qt-assistant-4.7.x versions. for less recent versions of the qt libraries (from 4.6 downward) it should be ok to ignore the (non-existing) use flag. On my case changing the use made computeprof start ok instead of crying out for a missing library. Reproducible: Always
The profiler comes with its own binary versions of the QT library, which are installed in /opt/cuda/computeprof/bin. I have x11-libs/qt-assistant-4.7.3 installed without the 'compat' USE flag, and computeprof works fine for me (ldd shows that it finds the library in the aforementioned CUDA-specific directory). Could you please try installing qt-assistant without the compat flag and pasting the output of `ldd /opt/cuda/computeprof/bin/computeprof` here?

You're right, I forgot we do different things for x86 and amd64. The problem should be fixed now.
