NPM install warns of peer requirement

[ekkis]

npm install grunt-bower-install --save-dev

warns that

npm WARN [email protected] requires a peer of grunt@~0.4.0 but none was installed.

which owes to a peerDependency in the package.json that was fixed by sirianni in this issue: #148

however, it seems that has not been migrated to NPM. the version installed is 1.6.0 - I don't know what version is most recent but when I click on the github link here: https://www.npmjs.com/package/grunt-bower-install it brings me to this other project (grunt-wiredep), which would have a different version. so I'm a little confused.

what should I do?
