LogStash-2.2 install via RPM not properly installing on RHEL5

I was following the [YUM Installation instructions](https://www.elastic.co/guide/en/logstash/current/package-repositories.html#_yum) listed in the link. However when I

```
# rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
error: https://packages.elastic.co/GPG-KEY-elasticsearch: import read failed(-1).
```

However, when I `wget` the GPG key, and import it that way, it works. Then I attempt to install the logstash binary after creating the repo file.

```
# yum install -y logstash

Then I try to ignore the `--nogpgcheck` to get it installed.

Same error, but it "installed". However, after installation, there is no `logstash` user, nor any of the other directories that should be created. I performed this same install on a RHEL6 server, and it worked just fine, no issues. Am I not doing something correctly?

Start with the linked YUM Installation instructions and the repository-file/RPM transaction on RHEL5, comparing them with the successful RHEL6 installation. Done means the GPG key and Logstash RPM verify correctly and installation creates the logstash user and expected directories.
