cookbook throws LoadError exception - which is not handled by rescue

[jjeffers]

When using this cookbook as part of a vagrant/chef-solo run, I see the following:

I would expect this if treetop had been yanked.

[michaelglass]

updated treetop to 1.5.3. Haven't dived in to see why this breaks, though.

[michaelglass]

please feel free to close if the issue goes away

I think that this error remains, it is just the second run which wil succeed, because then the gem "treetop" is installed. I have no idea, why despite the rescue-block this exception bubbles up. Anyone?
