After a mountain of hurdles, and learning curves today, ( its been fun ! ), I've built Bytecoin-Qt for Mac OS X
You can grab it here for now http://ge.tt/43pGKId/v/0?c
It was built on Mac OS Lion, x86_64. I wouldn't be surprised if it has problems on other versions, let me know if so, and apologies in advance if that is the case.
This does not work outside of your development computer, as you need to ship it with the libs and update the location in the app and dylibs inside your bytcoin-qt.app using install_name_tool. The instructions below show you how to do this from the part Linking the Application to Qt as Frameworks when it talks about the otool.
http://harmattan-dev.nokia.com/docs/library/html/qt4/deployment-mac.html
If you look at the output of otool -L Bytecoin-Qt.app/Contents/MacOS/Bitcoin-Qt. Those /opt/local/lib are on your computer only. Using cp -R you transfer the files to the Framework folder created in Bytecoin-Qt.app/Contents/ then use otool to change the location of the libs relative to the @executable_path.

If you check the output of otool -L Feathercoin-Qt.app/Contents/MacOS/Feathercoin-Qt you can see all the locations have been updated. The info is all in the link above. If anyone knows a better way of doing this than using the install_name_tool please let me know.
