Hi everybody:

I'm using Arch 64bit, and when I try to build mathGL, u3d is taken as a
dependency, but it fails to compile because of this error:

/usr/include/png.h:851:16: error: forward declaration of 'png_struct {aka
struct png_struct_def}'

It's highly probable this is due to Arch having upgraded to png1.5.
Is it possible to get this fixed? Thank you in advance.

César
