The problem

While I was configuring Ruby on Rails in a Red Hat (CentOS) with RVM I found a problem with the library libffi-devel because the package wasn't available via yum install, after search for a couple of days I found this solution.

Add rpmforge as a repository

Create a repo file in /etc/yum.repos.d/rpmforge.repo, you need to be an admin
Copy the following text.

#Name: RPMforge RPM Repository for Red Hat Enterprise 5 - dag
   #URL: http://rpmforge.net/
   [rpmforge]
    name = Red Hat Enterprise $releasever - RPMforge.net - dag
    #baseurl = http://apt.sw.be/redhat/el5/en/$basearch/dag
    mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge
    #mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge
    enabled = 1
    protect = 0
    gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
    gpgcheck = 1

Download the the rpmforge gpg key

 $ sudo rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt

Install the package via yum
```
 $ sudo yum install libffi-devel
```

Worked for me on:

Red Hat Enterprise Linux Server release 6.4 (Santiago)

Thank you

Thank you. I tried to install it on my el6. I've also tried to change el5 to el6 in links inside of your repo file and there's no libffi-devel!
It's only in el5 as you wrote.
So...
