I don't have access to a Debian system but some things come to mind:

a. The loop looks like it's in numarray.linear_algebra.

b. I changed numarray's setup to make the "config" command automatic for 
1.4.0.  That changes how the builtin lapack_lite module is 
configured/built which affects linear_algebra.

c. My impression is that debian builds numarray against external 
libraries so (b) shouldn't be the problem. 

Does the numarray tarball from source forge:

        
http://prdownloads.sourceforge.net/numpy/numarray-1.4.1.tar.gz?download

install and self-test OK using "python setup.py install"?
