numarray-0.4 doesn't currently support a two step build process because 
code generation,  which is required,  doesn't occur unless the install 
command is present.   Unfortunately,  code generation *always* occurs 
when the install command is present,  which defeats the purpose of a 
seperate build.   This problem has been fixed in CVS by making code 
generation the result of an explicit setup.py switch (--gencode) which 
makes it possible to generate code during a build command.

One work-around is the following:

1. First generate code (as a non-priviledged user) using "python 
setup.py install".  Control-C as soon as the code starts to build.

2. Do  "python setup.py build"

3. Edit setup.py,  commenting out the 2 calls to os.system() in the 
function prepare().  This prevents codegeneration during the "real" install.

4. Do "python setup.py install" as root,  noting that no new code is 
generated, and everything is already built.
