Xcode 4.6 throws an error when compiling berkeley db 5.3.21, so here's a ptach

When compiling, I got this error

I'm sure there are more elegant ways to patch this, but here are my steps:

1. curl -O http://download.oracle.com/berkeley-db/db-5.3.21.tar.gz

2. tar -xvf db-5.3.21.tar.gz

3. cd db-5.3.21/

We need to patch the code to make it compile on Xcode 4.6

1. curl -OL https://raw.github.com/narkoleptik/os-x-berkeleydb-patch/master/atomic.patch

2. patch src/dbinc/atomic.h < atomic.patch

Back to building BerkeleyDB

1. cd build_unix

2. ../dist/configure --prefix=/Users/bmcduffi

3. make

4. make install
