[yt-users] error launching yt: __gnu_cxx::__concurrence_lock_error

[John Wise]

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
