You can delete it. That is the directory specified by default to look 
for the ATLAS libraries which are a portable optimized LAPACK and BLAS. 
You don't need it on the Mac because you have vecLib, which is an 
Apple-provided version of ATLAS, pre-installed.

Yes, however, the ATLAS or vecLib libraries will be much, much faster.

Also modify the library_dirs_list and libraries_list variables, but keep 
these *_lite.c files commented out.

library_dirs_list = []
libraries_list = []

That way, Numeric will just pick up vecLib.

This is fixed in CVS.
