Hello All, I am trying to run Flay against my code base but am getting  
an error. I suspect it is related to the version compatibility but am  
not entirely sure. Any helpful ideas would be appreciated.

C:\prosrm\_2\atf\web\atf\ruby\>ruby -v  
ruby 1.8.5 (2006-12-25 patchlevel 12) [i386-mswin32]

Here is the error.
