EMS python error: Failed to import module

edit

I am just trying out the new functionality python plugin for the first time. However, I am encountering the following error the first time I run it:

** Severe  ** Failed to import module "pluginA"
**   ~~~   ** Python error description follows: 
**   ~~~   ** ImportError('libffi.so.6: cannot open shared object file: No such file or directory',)
**  Fatal  ** Python import error causes program termination

Is it the problem with missing library?
