the project.xml for VFS defines a dependency on version 0.1.17.  Try that 
and see if it works better for you.

<rant>
However, it seems to me that VFS should just bite the bullet and move to 
support newer versions of dependencies.  No one wants to be dependent on 
old buggy versions of libraries.  For those already using snapshots of VFS 
who don't want to update dependencies, then they can keep using the 
snapshot.  1.0 shouldn't be bothered with worrying about backward 
compatibility with unreleased versions.  That just means that future 
releases will have to be (unfortunately, legitimately) burdened by backward 
compatibility to 1.0, which, if not previously burdened with backward 
compatibility to snapshots using extremely out-of-date libraries, would be 
much easier to keep up with forward compatibility.  Yes, be liberal and 
release early and often, but make sure to take the same liberal stance in 
keeping up with dependencies.  Being conservative just leads to indictments 
(whoops, where did that come from?).
