The Toolbox packages have been rebuilt to correct this:  

<ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/libpng/libpng-1.2.8-7.aix5.2.ppc.rpm>
<ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/libpng/libpng-devel-1.2.8-7.aix5.2.ppc.rpm>

This is because the 1.2.8 package has an epoch number of 2.  I suspect the
1.2.32 package you are installing has an unspecified epoch number, and thus
RPM interprets its version to be a lesser value.

<http://www.rpm.org/max-rpm-snapshot/s1-rpm-depend-manual-dependencies.html#S4-RPM-DEPEND-VERSION-EPOCH>

The "Epoch: 2" line in the spec file was introduced in our first libpng-1.2.8
release, and almost certainly came from whichever Linux distribution's
package we based ours on.

It's unfortunate, but there's no way to remove the epoch now.  Doing so is
essentially a step backwards in version.  So, you can either force install
your 1.2.32 package, or first rebuild it to also have an epoch number of 2.
