Fredrik- This is a known issue. The tool currently only looks in certain locations or hints rather then spidering the whole hard drive (which could take a bit of time). If you have installed in a non-standard location (or are using a platform or version of software that hasn't been tested against) the tool won't find the component.
One way around this is manually enter more "hints" but this doesn't scale. I'm open to suggestions for handling this in a better way. matt ps-I assume you are running on windows. Where is python installed on your machine? -- http://mail.python.org/mailman/listinfo/python-list
