^As of Jan/13 are they all still required? Anything missing? Can I follow the instructions found here:
https://github.com/bitcoin/bitcoin/blob/master/doc/build-osx.txt ?
Yes, those instructions should work, but build-osx.txt tells you how to build bitcoind. Seehttps://github.com/bitcoin/bitcoin/blob/master/doc/build-osx.txt ?
https://github.com/bitcoin/bitcoin/blob/master/doc/readme-qt.rst
... for very similar instructions on building Bitcoin-Qt
readme-qt.rst suggests downloading and installing the `Qt Mac OS X SDK` from the QT website, but you can also:
port install qt4-mac
If something doesn't work, post here, or, even better, submit a patch for the documentation.
