    You've installed the binary version of #{gemspec.name}.
    It was built using Sqlite3 version #{BINARY_VERSION}.
    It's recommended to use the exact same version to avoid potential issues.

    At the time of building this gem, the necessary DLL files where available
    in the following download:

    http://www.sqlite.org/sqlitedll-#{BINARY_VERSION}.zip

    You can put the sqlite3.dll available in this package in your Ruby bin
    directory, for example C:\\Ruby\\bin
