hi, i have installed numpy (1.6.0) and scipy (0.9). , nose version is 1.0 i have intel cluster toolkit installed on my system. (11/069 version and mkl 10.3). i have machine having intel xeon processor and rhel 5.2 x86_64 platform. i have installed it with intel compilers. when i execute numpy.test and scipy.test, it hangs .
