Dependencies

[jrizza]

Hello,
When trying to do a "bower install", I got the following dependencies problem:

Unable to find a suitable version for webcomponentsjs, please choose one:
    1) webcomponentsjs#^0.5 which resolved to 0.5.5 and is required by paper-spinner#0.5.6
    2) webcomponentsjs#* which resolved to 0.5.5 and is required by core-component-page#0.5.6
    3) webcomponentsjs#^0.6.0 which resolved to 0.6.3 and is required by polymer#0.5.6

Prefix the choice with ! to persist it to bower.json

Could you please advice on this?
