Description

I encountered three problems when trying to build Avro today (via "./build.sh dist) to test interop:

• md5sum and sha1sum do not exist on Mac (md5 is the replacement for the former)
• If "build/" exists, you fail hard with "mkdir: build: File exists"
• If you don't have Java 5, Forrest fails with "'java5.home' is not defined. Forrest requires Java 5." and other good stuff.
