could you solve this?

No, I bounced around in some sort of dependency loop. We discussed it at a Ruby hack night last night and the idea was suggested that I try using 1.9.1 to see if I could get around the issue (on the theory that 1.9.2 is not "quite done"). What's your experience?

hmmm almost the same as you, I will try with 1.9.1 too.
My problem started with ruby-1.9.2-p0 and then I tried again with ruby-1.9.2-rc2 with no luck. I'll keep you updated if I find a solution.

Steven it's working for me on ruby-1.9.2-p136, thanks for your help

Confirmed, your solution of using 1.9.2-p136 fixes this issue. I wonder if it is a bug in hoe that needs to be reported.

This came in quite handy ;-)
