[SciPy-user] installation problems on Mac OS X

[Giovanni Samaey]

Hi all,

I am trying to install scipy on my shiny new macbook:
I followed instructions as on www.scipy.org/Installing_SciPy/Mac_OS_X/.
Installation of vecLib was done when the computer shipped (I found a  
vecLib).  The link to the vecLib on the instruction page is dead and  
I couldn't find a download on apple.com, so I don't know if that  
installation is complete, as the instructions ask.

Installation goes smoothly, byt scipy.test() gives 2 errors.  I tried  
both  python 2.4.4 and python 2.5.1; no difference. I have the most  
recent gfortran and I use gcc 4.0.   Scipy is taken from svn.
