CUDA Toolkit 5.0 NSight build errors on Mac OS X ML

问题

I have strange thing happened to my CUDA Toolkit 5.0. Few days ago both XCode and NSight Eclipse plugin lost ability to build even simplest CUDA related projects. XCode successfully building projects with custom build rule for C++ source files:

    nvcc "INPUT_FILE_NAME"

But console output shows that run failed

    error: executable doesn't exist: '/Users/geraldus/Library/Developer/Xcode/DerivedData/CUDA_Hello_World-gzfzqivvsmeamfghnovopxapkdsz/Build/Products/Debug/CUDA Hello World'
    error: failed to launch '/Users/geraldus/Library/Developer/Xcode/DerivedData/CUDA_Hello_World-gzfzqivvsmeamfghnovopxapkdsz/Build/Products/Debug/CUDA Hello World' -- SBTarget is invaliderror: failed to launch '/Users/geraldus/Library/Developer/Xcode/DerivedData/CUDA_Hello_World-gzfzqivvsmeamfghnovopxapkdsz/Build/Products/Debug/CUDA Hello World' -- SBTarget is invalid

And Eclipse NSight output always shows that .o file is missing.

    **** Build of configuration Release for project Simple CUDA RT ****

    make all 
    Building file: ../src/Simple CUDA RT.cu
    Invoking: NVCC Compiler

    nvcc -O3   "src/Simple CUDA RT.o" "../src/Simple CUDA RT.cu"

    make: *** [src/Simple CUDA RT.o] Error 1

How can I fix it? Is it a bug or my incorrect actions?

UPDATE [10:03 UTC 6 NOV 2012]

I've tried to rebuild CUDA samples this way:

    cd /Developer/NVIDIA/CUDA-5.0/samples
    make clean
    make

Everything was built without errors, binaries were successfully generated and they works. But still the same situation with XCode and Eclipse (even after reinstalling Eclipse and CUDA Toolkit)
