This may be a new line printed by Wien2k 13.1.  So likely an older 
version is being used.

This is similar to a previously reported error:

http://zeus.theochem.tuwien.ac.at/pipermail/wien/2012-January/016037.html

To know if it solves the problem or not, the user would have to apply 
the fix to the old verison or use 13.1.  If it doesn't solve the 
problem, the user could do more debugging, the Intel article at the 
following link might help:
