Public bug reported:
I was trying to use FeniCS actually. As I type the following in python
console, or run the demo programs(either C++ or Python), I get this
error:
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.

ImportError: /usr/lib/libmpi_f77.so.1: undefined symbol: opal_uses_threads
The last 'undefined symbols' are always there. However, openmpi seems to be
compiled with threads:
$ ompi_info -c | grep -i thread
