Could we use url("/absolute/uri/path") on @import ?

We transform our grunt task from grunt-sass to precss, and this code work well before.
```@import url('/static/css/database.css?some_query');```
Now we got this Error:
> Error: ENOENT: no such file or directory, open '/static/css/database.css?some_query'

and that ```?some_query``` is also a promblem.

In addition, how could use the newest version from npm ?  we just got 1.3.0 from precss.
