Questions like this should go to the mailing list, which I have cc'ed. My crystal ball tells me that you have /usr/gapps/exmatex/firedrake/firedrake/firedrake on your PYTHONPATH, whereas you should have /usr/gapps/exmatex/firedrake/firedrake. Therefore you have a name clash with the io module from the standard library and the one from firedrake is picked up instead. Those paths are rather awkward, which system is this?

Hi Florian,

Thanks for fixing the previous bug, now I have another. I'm trying to install Petsc via pip with --user enabled and I'm getting an error when importing gzip:

It might be the case that it's picking up some io.py file from my python path. This is a related issue: http://stackoverflow.com/questions/6315440/how-to-solve-attributeerror-when-...

Do you have any idea if this is the case?

Cheers,
