Can you branch perl-B-Utils for EL-5? If you aren't willing to maintain it for EPEL, I can take care of doing the branch and building the package. I can also become comaintainer for the package.
CVS request done in bug 474867. I took the liberty of adding you as comaintainer.
This one also needs perl-Test-Signature - cvs request is at bug 474864, but comaintainership is up for grabs if you want it.
imported and built.
