On other platforms, one has to edit the setup scripts to add the 
information about where the libraries are. The default fallback is to 
use the unoptimized version packaged with numarray.

The alternative would be to add autoconf-like capabilities to the setup 
script such that it could determine if the libraries were in the default 
places (and valid!), then fall back to the lite versions if not.

On the Mac, --use_lapack should have no adverse consequences, if I'm 
reading you right. On other platforms, numarray might fail to build 
correctly if one hadn't supplied the necessary information.
