[SciPy-user] Testing build before installing (numpy and scipy)

I am have a Mac running OSX 10.4.  My current installation of numpy and
scipy is broken, so I want to clean up and start from scratch. I just
installed Python 2.5.2 using a binary from the python web site.  I have
several questions:

1.  numpy's setup.py doesn't have an "uninstall" command.  Is that normal?
What is the standard way to remove something that I installed using
setup.py?  I want to clean out my Python2.4 broken installations.

2.  Having just installed python 2.5.2, I ran "setup.py build" in the
numpy-1.0.4 directory.  It generated lots of output, but I don't know if
everything built correctly.  There are some error messages about
_configtest.c having errors. Can I test the build without first installing

3. The instructions at
http://www.scipy.org/Installing_SciPy/Mac_OS_Xsuggest that the command
 "export MACOSX_DEPLOYMENT_TARGET=10.4" be given
before building scipy for OSX 10.4.  It is not clear from those instructions
if that macro is also used when building numpy.  I ran the build command
twice, once before defining the variable and once after defining it, and it
does change how numpy is built--well, it changes the names of some
directories, anyway.  Is this macro also supposed to be defined when
building numpy?
