If you are not using compass-specific components, such as its specific functions and mixes, I would suggest using the SASS translator to create CSS from SCSS.
SCSS file settings for viewing are pretty simple, and you don't need any rb files to create.
Sort of:
Program: C:\Ruby193\bin\scss.bat
Arguments: --no-cache --update $FileName$:$FileNameWithoutExtension$.css
Working directory: $FileDir$
Output paths: $FileNameWithoutExtension$.css
