/usr/lib/libmpi_f77.so.1: undefined symbol: opal_uses_threads

[Rongcui Dong]

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:

The last 'undefined symbols' are always there. However, openmpi seems to be compiled with threads:

$ ompi_info -c | grep -i thread
