compass.rb on project directory

I have a simple project with some scss files, I was using compass without config.rb to compile it to css.
But than I diceded to use one config.rb and I have named it compass.rb; and then the nightmare started.
I have reinstalled node, redownload all the dependencies nothing worked. In nutshel the misterious error:

``` internal/child_process.js:298
throw errnoException(err, 'spawn');
^

Error: spawn UNKNOWN

```

was caused by naming composer configuration file to compass.rb. After renaming it to something else like compassconfig.rb everything worked flawlesly.
I do not know it is a bug but is should be documented somewhere that you can not name your gulp-composer configuration file to composer.rb because it will fail to run.

Reproduce the failure with a project configuration named compass.rb, then compare it with compassconfig.rb. Start by reading node_modules/gulp-compass/lib/compass.js and lib/index.js at the stack-trace locations. Done means confirming the filename conflict and either documenting the restriction or defining a verified fix.
