Alien Bob's VLC fails to compile on newest current
 

looks like its related to libpng?

I had a similar problem with digiKam 1.1.0

Downgrading libpng solved my problem. The version I used was libpng-1.2.37 from the previous -current.
This is on 32 bit and I can't say what I might have broken by downgrading. Digikam is a dealbreaker for me though.

I have done no research on this so I can't say if there's a better fix.

I got interested because of digikam myself and searched for that. There is a patch for vlc at least upstream that might help (not tested by myself):

that got it. thanks
