refinery-edge gives error "no such file to load -- refinerycms-base (LoadError)"

I'm trying to run refinery-edge on my Ubuntu 10.04 64bit. I have RVM installed, created the gemset "refinery-edge", and followed the steps in the refinery website, but when I try to create the refinery project I get the following error:

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- refinerycms-base (LoadError)

Any help on this? thanks.

I've removed the guide as that was really for pre-0.9.9 and was asking for feedback via GitHub, please use the gem instead.

Currently the gem is up to date with edge.

Thanks
