Hi, not a simple problem :-)
root at testing:~# ldconfig -v |grep libpng
         libpng.so.3 -> libpng.so.3.1.2.8
         libpng12.so.0 -> libpng12.so.0.1.2.8

and for example:
  root at testing:~# nm -g /usr/lib/libpng.so.3.1.2.8 | grep \ 
png_create_write_struct
give :
00018f90 T png_create_write_struct
00018fd0 T png_create_write_struct_2
the exports of the shared lib are ok... mmm I have to investigate for a 
missing -lpng ... anyone with the same lib version and not with this 
problem outside ?
