Martin,

Fedora 6 has been out-of-date for a while and the repositories are no longer
available.  You might get lucky with 'yum reinstall numpy', but 'yum install
numpy' would not work because the repos are not around anymore.

If the package approach does not work (which is the preferred method), then
you need to install from the source (tar file).  Be sure to remove the build
directory first before running 'python setup.py install'.  This should
definitely work because you have cleaned up any possible conflicting
versions of numpy.  There is still a chance that your system is so
out-of-date that the build will fail.

As a last note, numpy does not require scipy (actually, scipy requires
numpy...).
