Package Error for Shibboleth SP Install

[Nicholas Geyer]

Hello,

I am attempting to install Shibboleth SP onto an Amazon VM, and when 
using # yum install shibboleth-sp.x86_64 I receive the following package 
errors.

--> Finished Dependency Resolution
Error: Package: shibboleth-sp-1.3-0.f.1.el3.rf.x86_64 (rpmforge)
            Requires: libcom_err.so.3()(64bit)
Error: Package: opensaml-1.1-0.b.1.el3.rf.x86_64 (rpmforge)
            Requires: libcurl.so.2()(64bit)

I haven't encountered this before. Am I perhaps using the wrong repository?

Thanks,
Nick
