Hi all,
Thank you all for your suggestions! It turns out that iraf is installed
on my work desktop and it somehow changes the F77 environment variable.
After changing it back to /usr/bin/f77 I was able to install SciPy.
However, when I now try to do 'from scipy.integrate import odeint' for
example, I get the following error message:
In [2]: from scipy.interpolate import odeint

undefined symbol: s_stop
It seems this is again related to the compiler, but I'm not sure what to
do about it. I have tried once more to set the NUMPY_ARGS to the
different options in the install script, and also to install yt without
SciPy and then install it using 'pip install scipy', but every time I
get the same error. My OS is Scientific Linux 6, by the way.
Cheers,
Caroline
