Description of problem:
Trying to install perl-Perl-Critic package from EPEL6 on RHEL6 causes the error below. This installs cleanly on RHEL5.

Version-Release number of selected component (if applicable):
n/a

How reproducible:
100%

Steps to Reproduce:
1. Install EPEL5 on RHEL5 and EPEL6 on RHEL6
2. Attempt to install perl-Perl-Critic on both systems
3. Observe that the above package installs cleanly on RHEL5 but fails on RHEL6.

Actual results:
--> Processing Dependency: perl(Exception::Class) for package: perl-Perl-Critic-1.105-2.el6.noarch
--> Processing Dependency: perl(Devel::StackTrace) >= 1.20 for package: perl-Exception-Class-1.29-1.1.el6.noarch

[-snip-]

Error: Package: perl-Exception-Class-1.29-1.1.el6.noarch (epel)
           Requires: perl(Devel::StackTrace) >= 1.20

Expected results:
Package and dependencies installed successfully

Additional info:
There are other modules that perl-Perl-Critic depends on which are missing from EPEL6. I will be filing a bug against those as well.
