[yt-users] SciPy installation problem

Hi Nathan,

I reran the install script from scratch every time, just to be safe. I 
think I actually may have it working now, after setting
NUMPY_ARGS="--fcompiler=g77". I've tried to load and use several SciPy 
functions and no errors so far. Hoping it stays that way!

Thanks again!

Cheers,
Caroline
