Hi JC,
I have a Mac, but I don't see those errors with the latest tip. I
installed yt with install_script sometime in September with gcc-4.2. It
has matplotlib v1.0.0 installed.
Maybe we can isolate this error to a particular import or program.
Does ipython load fine?
Can you manually import yt.mods in a python session?
Could you check whether a standalone python instance fails with the same
error when you do
import matplotlib
import h5py
import numpy
Let us know what you find.
Thanks,
John
