[racket] tool warnings from raco

When I invoke raco from the command line, it throws the warning:

> warning: tool "pollen" registered twice: "pollen" and #<path:/path/to/pollen>


This error also appeared on racket-dev in Jul 2013. At that time Matthew Flatt said:

But though I've tried deleting info-cache.rktd, the warning eventually returns.

The problem doesn't surface with other packages. It doesn't seem to affect how anything works.

It also might be a bug in this particular package, though I'm not clear how a package can mess with raco's registration scheme.
