downloaded libtheora directly from their website and compiled png2theora
successfully outside of Sage. I just retried installing from within Sage,
and it still cannot find libpng, and still fails to build png2theora . . .

libpng; is that right?
Yes. I have never developed on Mac OS, so I don't really know how to fix
it. This is the autoconf
check, used by libtheora to test for libpng:
{{{
dnl check for libpng
HAVE_PNG=no
if test "x$HAVE_PKG_CONFIG" = "xyes"
then
PKG_CHECK_MODULES(PNG, libpng, HAVE_PNG=yes, HAVE_PNG=no)
fi
AC_SUBST(PNG_CFLAGS)
AC_SUBST(PNG_LIBS)
}}}
It is very simple, and since the original source builds for you, this
should also work on Mac OS.
Maybe one could hard code the variables PNG_CFLAGS and PNG_LIBS in spkg-
install, but there should be a better solution.
