Error setting up rhc (red hat client tools)

I've installed rhc following the instructions on the Openshift website. All seems fine when I run gem install rhc and hgem update rhc but when I try to call rhc I get the following message below. I've tried reinstalling ruby and git, both 32 and 64 messages. I also thought the problem was a missing openssl but installing that made no difference.

I've run out of ideas and any help would be greatly appreciated

Thanks
