I do:  Why does it do this:

This is MetaPost, Version 0.641 (Web2C 7.5.4)
(test.mp (Diagram1.mp [1]
! A group begun on line 6 never ended.
<to be read again>
                   end
l.344 end
         ;
?

I installed the emp package, then ran 

  latex test.tex && mpost -tex=latex test.mp && latex test.tex

with the UML-demo diagram exported to Diagram1.mp.  Curiously, line 6 is
an empty line.
