No, I am not sure. But it sounds like pngmeta is trying to use  
symbols which do not exist in libpng. Perhaps these symbols used to  
exist and have been deprecated and removed. Perhaps they were private  
symbols that 3rd-party software never should have been using in the  
first place. Or perhaps these symbols should be there and there is a  
problem in libpng. I don't know. The developers of pngmeta should be  
able to figure it out though, and that's whom I'd recommended to  
contact, unless we have evidence that other libpng-requiring software  
is experiencing the same error.
