Sounds like gdkpixbuf was compiled incorrectly
and that the -lpng flag was not included when it
was compiled, so it's missing the functions that
libpng would have made available.

There's just the order of files to compile.  There are
various howtos, but nowhere specific.  You'll need to
search pretty hard.  

It's very important to read the configure output carefully 
and then the config.log output for the real reason why a 
dependancy failed.  

That way you'll fix these dependancy problems before having 
to start over when you get a runtime dependancy error.

Often you fix things by adding a lib to the mix with

     LIBS="-lnsl" ./configure --enable-shared .....

Good Luck,
