What type of system are you using?

What version of libpng is being used?

What version of GraphicsMagick are you building?

Please note that libpng 1.5 has a modified API.  Only the 
development/snapshot version of GraphicsMagick builds with libpng 1.5.

Sometimes it helps to inspect the config.log file to see what error 
message was produced by the compiler when the configure test failed. 
Often the error message can be quite helpful to understand the 
failure.
