[SciPy-user] numpy install fails

Hi all.

Have a numpy installation problem.  Wondering if anyone has seen  
something similar.

I'm installing with "python setup.py install --prefix=$HOME/usr/local  
 > setup.out"

There are some messages during the install about not finding Atlas,  
fine... no Atlas.  I understand it has it's own (potentially slow)  
built-in BLAS/LAPACK.  But when I try to import numpy, I get:
 >>> import numpy
import linalg -> failed: /dat/o1/cmaloney/usr/local/lib/python2.3/ 
site-packages/numpy/linalg/lapack_lite.so: undefined symbol:  

If I do an ldd on lapack_lite.so, it looks like all dependencies are  
met.  Anyone know where __mth_i_dsqrt is located, and why the build  
didn't complain about the unresolved symbol?


PS This is on a slackware box (on which I'm not admin).  Same install  
procedure works fine on my mac with fink:python-2.3.
