This is indeed required to get the color but my problem is that the
graphic do not get typeset at all!  As can be seen from the log file 

report >> mp terminal:
(/usr/share/texmf/metapost/context/base/mp-tool.mp
! Missing `=' has been inserted.
<to be read again> 
                    ,
l.51 vardef mpversioncmp(expr s,
                                c) =
! Missing `=' has been inserted.
<to be read again> 
)
[...a long list of such errors omitted...]

there is an issue with loading mp-tool.mp
Could it be that something related to mplib is not package in Norbert
Preining's packages?  Is there a particular file that I should look for?
