Rails3, compass and asset pipeline

Someone use compass?
Reading the docs, to use compass in a rails3 application I must run
“compass init rails /path/to/myrailsproject --using blueprint” (I want
to use blueprint).
But with asset pipeline I think it not necessary.
I’ve created a blueprint.css.scss file and put

@import “blueprint/reset”;
@import ‘_blueprint’;
@import “blueprint/fancy-type”;
@import ‘blueprint/liquid’;
@include blueprint;
@include blueprint-liquid-grid;

body {
@include blueprint-typography(true);
@include blueprint-utilities;
@include blueprint-debug;
@include blueprint-interaction;
@include fancy-type;

form {
@include blueprint-form;

That’s all.
Is it a correct method?
