Hi Carolyn,
I think Nathan had a similar issue just a couple days ago. His solution
was to create a png.cfg file in his yt source directory. That file should
just have a single line with the correct path to the libpng install,
similar to what's in the hdf5.cfg file. Someone strike me with lightning
if I messed that up.

I looked back in the email archive and found this exact same problem from John ZuHone. http://lists.spacepope.org/pipermail/yt-users-spacepope.org/2011-June/001652...
I wiped all png related stuff from the build and set INST_PNGLIB to 0 but I am still getting this error. Any ideas?
