Less Compile error with Laravel + Leafo + Basset

I have a project on Laravel that uses Bootstrap (via composer) and I recently moved to using Basset by Jason Lewis

When I tried building the basset collection application

dragonstone:rizwan$ php artisan basset:build application --force

I would get an error with mixins.

Starting development build...
Gathering assets for collection...

  parse error: failed at `.size(@width; @height) {` myapp/vendor/twitter/bootstrap/less/mixins.less on line 47 

Now, I don't use the stock less compiler shipped with Basset and prefer using the PHP LESS Compiler by Leafo.

The error as I figured was with the compiler not able to compile recursive mixin. However, the latest Leafo build, v0.4.0 fixes this and just pumping the version up in your composer.json should do the trick.

This is how my composer looks right now:

"require": {
    "laravel/framework": "4.0.*",
    "way/generators": "dev-master",
    "twitter/bootstrap": "dev-master",
    "jasonlewis/basset": "dev-master",
    "leafo/lessphp": "v0.4.0"
Say Thanks

Hi Rizwan - I had the same problem today, and I updated lessphp, but I still get the error. Any more ideas on how to fix this?

composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
- Removing leafo/lessphp (v0.3.9)
- Installing leafo/lessphp (v0.4.0)
Loading from cache

Composer looks happy to me, but... when I try to load my page, I still get:

parse error: failed at .size(@width; @height) { /myapp/public/assets/bootstrap-3.0.1/less/mixins.less on line 47

Looks like you have kept bootstrap in the public assets and are not loading it through composer. Can you try loading bootstrap through composer too.....

I am not really sure if that is the reason, but sounds legit to try once....
