I *think* that scipy still uses Numpy not Numeric interfaces, though I may 
have this backwards...

There is no 'python-numpy' package in the sl5 standard repos, since at 
least sl52 there has been a 'numpy' package which was version 1.0.4 in 
sl52 and 1.2.1 in sl53 and later.

[ We used to build numpy/scipy packages long long ago, which is why I half 
remember this ]

Yes, scipy depends on numpy (not python-numeric or python-numpy)...

I think the confusion is that you had installed a python-numpy which 
provides the feature numpy, which scipy wants so unless you have numpy 
installed removing python-numpy will need to remove anything that depends 
on it (including scipy)...

You mention python-numpy when the question was about python-numeric :-)

I'd suggest removing the python-numpy and any rf/dag versions of 
python-numeric from your repos and do the tests with just the sl5 repos 
enabled...
