[SciPy-user] CPU you selected does not support x86-64 instruction set

Hello:
I just installed a new version of numpy from svn on my 64-bit, Fedora
8 machine, but cannot get scipy to install.  I get the error: "CPU you
selected does not support x86-64 instruction set", which others have
had on this list.  Suggestions have been to install a new version of
numpy (which I did) and to use a gcc version > 3.4 (which I have).  So
I am stuck.  Any suggestions?

Here is a bit of information on my machine:
