My [ports-list.txt](http://quickgit.kde.org/?p=clones%2Fwebsites%2Fbuild-kde-org%2Fkaning%2Fmp-osx-ci.git&a=blob&h=425e1945e1073076c95e8d35e9ec5d31ee7db710&hb=d045a3e6e65fad1f0d85cbd799521710ef4acea4&f=ports-list.txt) states that there are quite a few dependencies needed for qt5:
```
zlib openssl dbus jpeg tiff libmng libpng mysql55 pkgconfig icu pcre libiconv sqlite3
```
* I think we can do (for a start) without `mysql55`.
* Also we should skip `pkgconfig`, as it doesn't exist on a bare OSX system.
* System libs exist for `zlib`, `openssl`, `jpeg`, `tiff`, `pcre`, `iconv` and `sqlite3`.
* These should be shipped with `qt5`: `libmng`, `libpng`
* Don't know what to do about these: `icu`, `libiconv`, `dbus`
