When I tried installing `perl-Net-SNMP`, I get the dependency error below :

```
# yum install perl-Net-SNMP

...

--> Processing Dependency: perl(Digest::HMAC) for package: perl-Net-SNMP-5.2.0-4.el6.noarch
--> Processing Dependency: perl(Digest::SHA1) for package: perl-Net-SNMP-5.2.0-4.el6.noarch
--> Finished Dependency Resolution
Error: Package: perl-Net-SNMP-5.2.0-4.el6.noarch (epel)
           Requires: perl(Digest::HMAC)
Error: Package: perl-Net-SNMP-5.2.0-4.el6.noarch (epel)
           Requires: perl(Digest::SHA1)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
