Unable to install on WinXP with Ruby 1.9.1p129

[jonforums]

Using 1.9.1p129 from http://rubyinstaller.org/downloads/ along with the MSys/MinGW-based DevKit on a WinXP Home SP3 system, I get the following.

At this early stage, I suspect that Windows usability may not be a high priority, but when I saw that the error dealt with trying to install the 'rip' executable to /usr/local/bin I thought this might be an easy one to knock down.
