Well, I won't pretend to speak for the developers on this one.  But I
strongly suspect it is just too hard to find all possible LAPACK
distributions;  the default numarray setup should be self contained even
if somewhat slower.  The current version of Numeric also defaults to its
own built-in BLAS and requires editing setup.py to use a different one.
