[yt-users] installation problem: unrecognized command line option ‘-faltivec’

[Nathan Goldbaum]

Hi Jean-Clade,

I haven't seen that before.  I guess you're trying to build scipy using the install script?  On OS X you should be able to build scipy using pip.  A quick workaround for this error would be to delete the broken installation tree and then rerun the install script with INST_SCIPY=0.  This won't build LAPACK.

Once that finishes you should be to install scipy using pip:

$ pip install scipy

That will build scipy using the accelerate/veclib library included with OS X.

I have a laptop with 10.8.2 installed here and I'll try to reproduce the error you're seeing sometime soon.  To remind me, would you mind filing a bug about this on our bugtracker?
