prototype-1.7_rc2 unable to place inside of asset_package

[rockrep]

I have to exclude prototype.js (v 1.7_rc2) from the asset package, and load it with javascript_include_tag in order to get prototype to load. The rake task asset:packager:build_all succeeds with prototype in the package, but it still fails to load.
