[Wien] MKL FATAL ERROR

Dear all
I tried to use -static as Peter (and Gerhard previously)
suggested...and it worked!!
The problem disappeared and I was able to run all the test cases to
their completion.
The second suggestion about the LD_LIBRARY_PATH I had already followed, adding:
LD_LIBRARY_PATH=" /opt/intel/mkl/10.1.0.015/lib/em64t:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH
to .bashrc, but not in the line added by Wien2k, which i could
uncomment. I should try that to link dynamically.
Thank you very much for your help!
Best regrads
