[NTG-context] metafun color broken?

After posting this problem I did probe a lot further in this and a  
similar problem.
As I reported shortly, the problem goes away when solely replacing in  
supp-mps.tex the line
\ifx\TEXEXECcommand \undefined \def\TEXEXECcommand{texmfstart  
texexec} \fi
\ifx\TEXEXECcommand \undefined \def\TEXEXECcommand{texexec} \fi
This gives me the impression it might not be in context itself,  
especially since to my (inexperienced) eye there are no or few  
changes between the working and nonworking versions that might  
explain the problem.
It might be the change from the perl to the ruby scripts with a  
problem in one of the latter.

I expect Hans or Taco to react soon with there usual speed and will  
await for their comments first.

I usually do this when in doubt if my code is right.
But in this case formerly perfectly working code is suddenly broken.
And of course I need to run my production and development runs on my  
own machine, so I have to solve it for that one.
