More on this gist:
me: Ah hah! Before you can run bundle, first you need to do:
'sudo rvm pkg install openssl
The output from that will tell you to do:
rvm reinstall all --force
I had a little funniness with a .rvmrc in git/qless that wanted ruby-1.9.3-p392 instead of p194.
I removed that .rvmrc.
Dan: Is it happy now?
me: Let me get redis installed, then I'll try starting qless and hitting its web page.

me: Oh, and the first two chunks of the freshscape gist definitely need to get run before any of the qless gist.
...Because the qless gist relies on the RAID setup.

me: And I think the /etc/ needs to go away from:
sed -i "s#dir ./#dir $REDIS_DIRECTORY#" /etc/redis.conf
Because you cp redis.conf /etc/redis.conf on the next line.
