Comment (by andrejohn.mas@…):

 Trying to do a build of 0.7.83 using current Portfile, with changed
 version resulted in some issues, notably a dependency on libzen (non-
 optional per the mediainfo team) and he suggested I take a look at the
 Homebrew formula for building:

 https://github.com/Homebrew/homebrew/blob/master/Library/Formula/media-
 info.rb

 If I have time I'll see what I can do, but this is here to help anyone
 trying to update this port.
