Comment (by jpflori):

 Cannot really work on this one as I don't have access to Mac OS X.

 Maybe mercurial links to something outside of Sage which itself links to
 libpng which at runtime is resolved as our libpng, but unfortunately the
 libpng we ship is less capable than the system-wide one and the symbol
 lookup fails.

 Could you post the mercurial log?
