OK, just to provide more info:  I've confirmed that linking with gcc, even if 
you explicitly ask for the library that contains that symbol, doesn't work. 
  However, if I manually rerun the link steps as:

icc -pthread -shared 
build/temp.linux-ia64-2.3/scipy/base/src/multiarraymodule.o -o 

and then run the 'python setup.py install' step with this rebuilt 
multiarray.so object, the problem goes away.

So the question really is: how do we get scipy.distutils to use icc as the 
LINKER and not to use gcc at all?  Thanks for any pointers...
