OpenCV 2.4.0 ebuild contains check to disable CUDA support if GCC > 4.4 is used. This is no longer correct for new versions of CUDA and OpenCV.

This version of OpenCV can be built with CUDA 4.1 and GCC 4.5.3.

With dev-util/nvidia-cuda-toolkit-4.1, version check seems to be the following in /opt/cuda/include/host_config.h:
#if defined(__GNUC__)

#if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 5)

#error -- unsupported GNU version! gcc 4.6 and up are not supported!

#endif /* __GNUC__> 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 5) */

#endif /* __GNUC__ */
