Show changes in output

[Kurt]

Hi !

I use LyX on a Mac and on a PC. I use the track changes function and  
would now like to include the changes in the output file (pdf).  
Unfortunately I don't manage to. The wiki page

http://wiki.lyx.org/Tips/ChangeTrackingLyx1-3-2

says one needs to install dvipost, which does not install on my Mac,  
and I don't have an idea of how to install dvipost on a PC. Any  
suggestions please?

Best regards,
Kurt
