How to rebuild coffescript package in Meteor dev checkout?

Hi -

I was trying to debug a problem that was coming up during a build of a coffeescript package.

I followed the instructions to get my developer build of Meteor working.

But when I made a change to packages/non-core/coffeescript/etc it didn’t rebuild and reflect that when I ran <meteor-checkout>/meteor

What do I need to do to get it to rebuild those packages?

OK just tried again and it worked this time. All I can imagine is that somehow my .meteor/versions file had a hardcoded version of that package so it didn’t get the package that was included in the dev build.
