I think these warnings result from you having erlang object code files (.beam files) and erlang source code files (.erl files), and erlang noticing that the source code files have been modified after the corresponding object code files, therefore the object code files are out of date.
I'm not sure what might have led up to this situation occuring for you - it doesn't seem to have been reported before. But deleting the source files in rabbitmq_server-2.1.0\src should fix it - they are not required for rabbitmq-server to function.

We always build RabbitMQ releases with quite an old version of erlang anyway, in order to be able to run on a wide range of erlang releases.
