Have a strange problem in that I have a Rake task that seems to be using multiple versions of Ruby. When one fails, it seems to try another one.
Details
MacBook running 10.6.5
rvm 1.1.0
Rubies: 1.8.7-p302, ree-1.8.7-2010.02, ruby-1.9.2-p0
Rake 0.8.7
Gem 1.3.7
Veewee (provisioning Virtual Machines using Opcode.com, Vagrant and Chef)
I'm not entirely sure the specific details of the error matter, but since it might be an issue with Veewee itself. So, what I'm trying to do is build a new box base on a veewee definition. The command fails with an error about a missing method- but what's interesting is how it fails.
Errors
I managed to figure out that if I only have one Ruby installed with RVM, it just fails. If I have more than one Ruby install, it fails at the same place, but execution seems to continue in another interpreter.
Here are two different clipped console outputs. I've clipped them for size. The full outputs of each error are available as a gist.
One Ruby version installed
Here is the command run when I only have a single version of Ruby (1.8.7) available in RVM

Multiple Ruby Versions
Here is the same command run with three versions of Ruby available in RVM. Prior to doing this, I used "rvm use 1.8.7." Again, I don't know how important the details of the specific errors are- what's interesting to me is that there are three separate errors- each with it's own stacktrace- and each in a different Ruby interpreter. Look at the bottom of each stacktrace and you'll see that they are all sourced from different interpreter locations-
First ree-1.8.7, then ruby-1.8.7, then ruby-1.9.2:

It isn't until we reach the last installed version of Ruby that execution halts.
Discussion
Does anyone have any idea what's going on here? Has anyone seen this "failover"-like behavior before? It seems strange to me that the
first exception would not halt execution as it did with one interpreter, but I wonder if there are things happening when RVM is installed that we Ruby developers are not considering.
