You misinterpreted the given information. You will not find any information regarding these patches in the perldelta, as this document describes the changes in perl itself between versions. E.g. what has been changed or added from 5.8.7 to 5.8.8.

What you are looking for is what RedHat changed under the hood to 5.8.8, and that should be found in the description of those patches - if available at all.

FWIW, it could be that there are no visible changes at all. I recently delved into such a patch from OpenSUSE, and found that the only change was textual in the build description file.

My hunch is that this patch from RedHat will not have any influence on your modules at all.
