Thanks for the reply. 

After I replaced 'Function' by 'Coefficient', the compilation went fine except at the last step, it complains about the following:


Unable to generate DOLFIN wrappers, missing module dolfin_utils.wrappers.

*** FFC: Unable to generate DOLFIN wrappers, missing module dolfin_utils.wrappers.
*** FFC: To get more information about this error, rerun FFC with --debug.


Best,
Chong

Replace 'Function' by 'Coefficient' in your .ufl files and you should
be ok.
