I just reran the setup script and confirmed that the png.cfg file is being created by the current version of the install script in the development branch.  Perhaps it's not being created on some systems due to updating from an old version of yt that did not build the png.cfg file?

It looks like the png.cfg functionality was added by Matt in the geometry_handling branch, so I think that makes sense, seeing as these changes were merged in quite recently (I don't have the mercurial-fu to figure out exactly when that happened).

Nathan, any idea why these files didn't get created?

In fact the hdf5.cfg and png.cfg files are identical.

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.html

I wiped all png related stuff from the build and set INST_PNGLIB to 0 but I am still getting this error.  Any ideas?
