    You've installed the binary version of #{gemspec.name}.
    It was built using MySQL 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://dev.mysql.com/get/Downloads/MySQL-5.0/mysql-noinstall-#{BINARY_VERSION}-win32.zip/from/pick

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