Hi,
after previous problems, I finally got the svn version of scipy/numpy to 
build and install.

This was using gfortran 4.0.2 (I had to remove files 
scipy/splinalg/eigen/arpack/ARPACK/SRC/snaupe.f and 
scipy/splinalg/eigen/arpack/ARPACK/SRC/dnaupe.f
because they had zero size, and were causing gfortran to segment.

It then went on to install fine.

However, I still have the problem with scipy.special.kv:
>>> scipy.special.kv(6./5,1.)
0.70066931017889988
>>> scipy.special.kv(6./5,1.)
0.70066931017889988
>>> scipy.special.kv(6./5,[1.,1.])
array([ 0.70066931,  0.70066931])
>>> scipy.special.kv(6./5,1.)
1.0989331402998264e+151
>>> scipy.special.kv(6./5,1.)
0.0
>>> scipy.special.kv(6./5,1.)
1.0185579799004822e-312

So, the problem still exists.

lapack/atlas were compiled with the same gfortran.

This is Suse 10.0, x86_64 platform.

Other ufuncs, eg scipy.cos work fine.

Thanks...
