Dear Sir/Madam,

I am trying to get Firedrake up and running on the Isca cluster at Exeter.  The standard install method (i.e., executing 'python3 firedrake-install') does not work, however, we have managed to install Firedrake by developing an install script that loads modules manually, that sets a number of petsc options, and that passes a number of extra options to firedrake-install.

However, when I try and run a simulation on Gusto I get the following error: 

Traceback (most recent call last):

  File "./examples/boussinesq_2d_lab.py", line 1, in <module>

    from gusto import *

  File "/gpfs/ts0/home/pb412/firedrake-20171026/src/gusto/gusto/__init__.py", line 11, in <module>

ImportError: /gpfs/ts0/home/pb412/firedrake-20171026/lib/python3.5/site-packages/netCDF4/_netCDF4.cpython-35m-x86_64-linux-gnu.so: undefined symbol: _PyThreadState_UncheckedGet

So it looks like there is some problem with the netCDF4 library.
