Comment 5 for bug 481833

Here it is:

Mac OS X (Darwin) instructions
----------------------------------------

You'll have to have these components installed:
- XCode
- MacPorts
- Certain MacPorts ports:
  $ sudo /opt/local/bin/port install bzr scons pkgconfig libglade2 libnotify boost

For a successful build, you'll have to explicitly specify MacPorts header
dir so that boost lib gets found (make sure to start with a fresh source
tree):

$ export CXXFLAGS=-I/opt/local/include
$ scons PREFIX=<prefix, f.e. ~/linuxdcpp>
$ scons install

To run linuxdcpp without missing icons, you'll have to install hicolor
GTK theme from http://icon-theme.freedesktop.org/releases/:

$ wget http://icon-theme.freedesktop.org/releases/hicolor-icon-theme-0.11.tar.gz
$ tar -zxvf hicolor-icon-theme-0.11.tar.gz
$ cd hicolor-icon-theme-0.11
$ ./configure
$ sudo make

Finally, run linuxdcpp either by starting it from Terminal, or
by double clicking on it in Finder.
