It's meant for people building GTK+ in very specialized circumstances,
and not recommended; PNG is the recommended image format that most
apps expect to be present. It isn't expected to work without some special 
work. If you compile GTK+ twice, once with libpng, then a second
time disabling libpng, you'll probably get a working GTK+ without the
dependency.
