Capistrano error deploy.rb: warning: failed to set environment variable

Running Capistrano from a WinXP machine. Deploying from Beanstalk repo to Linux box.

Everything works perfectly with the exact same capfile and installation details on my Mac OS X 10.6 machine, but I can't get things to function correctly on the Win XP machine.

Looked at lines 95 and 104 of deploy.rb since these seemed to cause some issues, but wasn't able to figure anything out. At a bit of a loss :-[

The exact log of the deploy attempt is:

The answer for this problem turned out to be that there was a bug in the specific version of Ruby 1.8.7 that I was using, affecting Win XP but not Win Vista and Win 7.
