bitcoind 0.7.2

provides a brand new formula for bitcoind which can be built with/without IPv6 support (with is the default) and with/without UPnP support (without is the default due to additional dependancies).

though the bitcoin project (http://bitcoin.org/) does provide a pre-built OS X version of its client, it does not bundle bitcoind with the client.

this formula has been heavily adapted from WyseNynja's unofficial bitcoin brews (https://github.com/WyseNynja/homebrew-bitcoin)
