Given that the error pertains to the /usr/local directory, you may have 
python installed in more than one location. So please check the path to 
python is being used as a normal user and as root - such as doing the 
'which python' command.

Really you must remove the 
'/usr/local/lib/python2.4/site-packages/numpy/' directory and other 
numpy files *before* installing numpy and scipy.  Then you probably need 
to specific the full path to the python you want to use - something like:
$/usr/local/bin/python setup.py install

While I doubt that your current setup is controlled by your Fedora 6 
package manager, you should be able to determine if numpy was originally 
installed via the distro by querying the installed packages. Your 
package manager should show it as installed if you search for numpy or 
just use rpm:
$rpm -qa | numpy

If so, then you probably can do:
$yum reinstall numpy

You may be able to yum or whatever package manager to install both numpy 
and scipy if these are both in Fedora 6 repositiories (they are for 
Fedora 13). For example, as root:
$ yum install numpy scipy
