[yt-dev] Setup script uses the wrong libpng headers

[Nathan Goldbaum]

Hi all,

I've just run into an odd issue.  I'm using Matt's yt-extJS4 fork to make 2D plots.  In doing so, I discovered that png_writer.so is being compiled with the wrong libpng.h header.

This produces errors that look like:

libpng warning: Application was compiled with png.h from libpng-1.5.4
libpng warning: Application  is  running with png.c from libpng-1.2.43
libpng error: Incompatible libpng version in application and library
Segmentation fault: 11

 Does anyone know why the setup script isn't finding the libpng headers that come with yt?

Thanks for your help,

Nathan
