centos4 repo missing from deb.torproject.org
When doing a **yum update** on a centos4 server with tor installed I get the following:
```
root@svr [/]# yum update
Setting up Update Process
Setting up repositories
http://deb.torproject.org/torproject.org/rpm/centos4/repodata/repomd.xml: [Errno 14] HTTP Error 404: Not Found
Trying other mirror.
Cannot open/read repomd.xml file for repository: torproject
failure: repodata/repomd.xml from torproject: [Errno 256] No more mirrors to try.
Error: failure: repodata/repomd.xml from torproject: [Errno 256] No more mirrors to try.
```
I can confirm that the [centos4](http://deb.torproject.org/torproject.org/rpm/centos4/) folder does not exist on the server.
