Re: mplib errors

[Hans van der Meer <H.vanderMeer@uva.nl>]

Olivier: What system do you use? I am using MacOSX and in july this  
year I mailed about the error below:

Sounds familiar? If you are also working on MacOSX(10.5.x) then I  
should expect the problem to be platform specific. I had some  
discussions with Taco Hoekwater about this problem, but we never  
solved it and I have no inkling of its cause. Since I am not well  
enough acquainted with the code behind mplib and friends, I had to  
fall back on using MKII and putting MKIV aside.
But I guess the solution to this problem is pressing, since we cannot  
have one platform falling out on ConTeXt.
