Comment (by p.bro@…):

 As an aside: The last released dot2tex version is from 2009. The code has
 since moved to github https://github.com/kjellmf/dot2tex with a number of
 patches. Apparently a new release is in the making (see
 https://github.com/kjellmf/dot2tex/commits/master) so it might be
 worthwhile monitoring github...
