For reference, here is a script that builds a static univeral libpng library,
and then copies it into /usr/local/lib with a u appended to the filename
(libpng12u.a):

In order for it to work, png.h has to be modified. In 1.2.18, line 497 needs to
be changed like so:
Old:
#ifdef PNG_USE_PNGGCRD
New:
#if defined(PNG_USE_PNGGCCRD) && defined(PNG_HAVE_MMX_COMBINE_ROW)
Run buildpngu.sh while in the main directory of the libpng source distribution.
I used it with 1.2.18; hopefully it will continue to work.
