Are you manually compiling lablgtk or using one of the MacPorts  
ports, lablgtk or lablgtk2?

If you're using one of the existing ports, please file a ticket in  
the issue tracker and assign it to the maintainer of the port. You  
should also include more of the output showing what's actually  
failing, including what command you originally typed to get to that  
error.

If you're compiling by hand, why not use the existing ports?

If you're installing by hand: What's your PKG_CONFIG_PATH? Does it  
include the place where cairo is installed?

Here too, the PKG_CONFIG_PATH would enable cairo to know where libpng  
is.
